• Double-click the MPPT Solar Charge Controller Workshop.exe file in the BIN folder to open the MPPT Solar Charge Controller Workshop software, as shown below:

The loading interface is as follows:

After the loading has finished, the home page is shown as follows.

• The home page consists of four parts: Menu, Shortcut, Recent Project, and Project Example 1.
  1. The Menu includes four options: Project, Language, Tool, and Help.
     • The Project option includes New Project, Open Project, Save Project, Save Project As, and Workshop Example. Users can create a new project, save the currently opened project, or even create a new project example.

After clicking on a project, a red box will appear to indicate the current project, with its output specification, input specification, and other descriptions displayed on the right. Clicking “Open” can quickly open the corresponding project. If users have not created any project for the first time using the platform, this list is empty.
  4. The Project Example list shows the basic information of the 200W and 800W MPPT solar charge controller project exampలెస్.
• Click and then save the project example to enter the configuration interface, where users can modify parameters on the basis of the example to quickly complete the desired project configuration.

Project Configuration Description

• There are five items for the Project option: New Project, Open Project, Save Project, and Save Project
• As and Workshop Example, which is described in the following.

కొత్త ప్రాజెక్ట్

• Click the New Project item in the Project option to open the New Project interface. Fill in the project name and project path.
• Then click “OK” to create a new MPPT solar charge controller project and generate the prjsc project files under the selected path, as shown below.
• After creating a new project, enter the parameter and functional configuration interface. There are six steps in order: MCU Selection, Power Circuit Frame, Tracking Algorithm, MPPT Solar & DC Charging, Battery Pack & Load, and Protection Function Settings. During any step, users can click “Home Page” to return to the home page.

The following figure shows the MCU Selection interface:

• On the MCU Selection interface, users can select the MCU part number, frequency, package, communication interface, baud rate, parameter freezing, and the MPPT solar charge controller solution, as shown in ①.
• The “Parameter freezing” option indicates whether to enable the emulation of EEPROM in Flash to store communication setting parameters. There are 200W and 800W two MPPT solar charge controller solutions to choose from.
• According to the selected solution, some subsequent parameter ranges will be limited, the corresponding project example will be used as the template, and the corresponding MCU pin diagram will be displayed below it, as shown in the following figure.
• After the MCU Selection has been finished, click “Next” or directly click the interface name on the left to enter the Power Circuit Frame interface, which contains the Topology Structure and Parameter Settings interfaces.

The following is the Topology Structure interface:

• On the Topology Structure interface, as shown in ②, choose Synchronous Buck-Boost, Synchronous Buck, or Synchronous Boost according to the circuit structure of the evaluation board used, then the corresponding topology diagram will be displayed below. Select a proper switching frequency based on the inductance used.
• The switching frequency and the duty level correspond to each other, and the multiplication of the two equals the frequency of the MCU, so when one of them changes, the other one will also change synchronously.
• The dead time selection depends on whether the gate driver integrates a dead time control circuit or not.
• If not, the dead time option must not select 0, because a certain time period is required to prevent the high and low-side MOS from being turned on simultaneously.
• After the topology structure configuration has been finished, click “Next” to enter the Parameter Settings interface, as shown below.
• The Parameter Settings interface includes three parts: ③ Duty range, ④ Starting dropout voltage, ⑤ Initial duty. If the Synchronous Buck-Boost topology structure is selected, it is divided into four sub-modes: Buck, Boost, Buck-Boost, and Boost-Buck. The duty range part limits the upper and lower duty values for these four sub-modes. The starting dropout voltage and initial duty parts determine the establishing conditions for the initial state at power-on. Generally speaking, start in Boost mode when the input voltage is far less than the output voltage, start in Boost-Buck mode when the input voltage is slightly less than the output voltage, start in Buck-Boost mode when the input voltage is slightly greater than the output voltage, and start in Buck mode when the input voltage is far greater than the output voltage, which can be set in the starting dropout voltage part. In order to start up smoothly, subtract an appropriate difference from the input voltage for the Boost and Boost-Buck modes or subtract an appropriate difference from the output voltage for the Buck and Buck-Boost modes so as to control their initial duty. It is recommended to use the default parameter setting values on this interface. If it does not start up properly, send out data through The ART and check whether the failure is caused by inappropriate start mode and duty value settings. Then adjust these parameters according to the actual test situation.
• After all the Power Circuit Frame configurations have been finished, enter the Tracking Algorithm interface:
• On this interface, users can select the MPPT algorithm and adjustment period, as shown in part ⑥. Currently, the platform provides two MPPT algorithms, which are the perturbation and observation method and the conductance increment method. Their corresponding features and curves are displayed in the upper area. In addition, users can ⑦ select a fixed duty step size or a changed duty step size to change the MPPT adjustment rate. At the lower right ⑧, users can modify the change values of the power, curren,t and voltage to adjust the MPPT accuracy. It should be noted that if the step size is set too large or the change values are set inappropriately, it will cause abnormal operation, so it is recommended to use the default values for this part of the configuration.
• After the Tracking Algorithm configuration has been finished, enter the MPPT Solar & DC Charging interface, as the following shown.
• On the MPPT Solar & DC Charging interface, ⑨ set the maximum and minimum input power and the input voltage range. Since the input device could be a PV board or some other regulated power supply, it is required to set the corresponding maximum input current in parts ⑩ and ⑪. When a PV board is connected, the selected MPPT algorithm is executed to track the maximum power point. For this situation, users can choose whether to perform the “Global tracking” and “Only recognizes solar input” functions.
• When “Global tracking” is checked, the PV board voltage will be continuously pulled low to a percentage of the open-circuit voltage to retrieve the global maximum power point, which prevents tracking to the local maximum power point. When “Only recognizes solar input” is checked, the DC charging configuration below will be set to an unavailable state, and then the maximum power point tracking will be performed regardless of the input device connected. If “Only recognizes solar input” is unchecked, when an adaptor or a regulated power supply is connected, the constant current charging will be a percentage of the actual maximum input current.
• Due to errors in sampling, users need to select an allowable fluctuation range for the maximum input current.
• After the MPPT Solar & DC Charging interface has been configured, enter the Battery Pack & Load interface, which includes the Parameter Settings and Charging Process. The following figure shows the Parameter Settings interface.
• On the Battery Pack & Load interface, ⑫ configure the basic charging information of the battery pack, such as battery type, battery voltage range, full charge voltagఇ, వాల్యూమ్ కిందtage, maximum charging current, etc. The battery pack temperature detection is disabled by default. To use this function, users should check this option and ensure that the corresponding NTC on the evaluation board has been soldered. ⑬ The purpose of temperature compensation is to ensure that the charging effect of the battery is consistent at different temperatures, and it is disabled by default. ⑭ The load configuration part allows to selection of the constant voltage output mode, which can provide a power supply for devices without connecting the battery. If there is a large-capacity filter capacitor connected to the device input terminal, it is necessary to check the “Soft start” function and set the appropriate initial voltagఇ మరియు వాల్యూమ్tage increment; otherwise, the overcurrent protection may be triggered by the instantaneous large inrush current.
• Note that for the constant voltage output type, users need to first modify the initial operating mode through the communication command or through the generated Keil or HT32-IDE project; otherwise, it will implement the default operating mode to charge the battery.
• After the Parameter Settings have been finished, enter the next step, Charging Process, as shown below.
• The Charging Process interface graphically shows the four stages of battery charging, as shown in ⑮. For the lead-acid battery, the charging process is trickle → constant current → constant voltage float voltage. For the lithium battery, the charging process is trickle → constant current → constant voltage → recharge. The voltage, current, and charging time of each stage are set in this part. Additionally, the LED indication for different charging stages can be set in part ⑯. LED1 represents the red indicator, LED2 represents the blue indicator, and LED3 represents the yellow indicator. If this function is not checked, the LED indication will be executed by the defaut setting.
  If the function is checked, the LED on/off status for each charging stagఇ అనుకూలీకరించవచ్చు.
• After all the Battery Pack & Load configurations have been finished, enter the Protection Function Settings interface, as the following figure shows.
• The Protection Function Settings consist of ⑰ input voltage protection, ⑱ output voltage protection, ⑲ over temperature protection, and ⑳ over current protection.
• The trigger condition, protection delay time, and protection release condition of these protection functions are configured on this interface.
• After all of the above interfaces have been configured, click “Finish” to generate a Keil project and an HT32-IDE project, which share a project file.
• Open the project in either way, connect the e-Link32 Pro to the evaluation board, then click the compile and download buttons to download the code.

ప్రాజెక్ట్ తెరవండి

• After clicking the Open Project item in the Project option, a window will pop up to select the file path. Then select the desired prjsc file ప్రాజెక్ట్ తెరవడానికి.

ప్రాజెక్ట్ను సేవ్ చేయండి

• During the project configuration, it is required to save the project in time if any parameters are modified; otherwise, a prompt window as follows will pop up when you return to the home page or close the platform directly.

Save Project As

• Click the Save Project As item, a window will pop up to select the path. Then fill in the file name and click “Save” to save it as another prjsc project file.

Workshop Example

• This platform has provided the 200W and 800W MPPT solar charge controller project examples, which can be selected through the Workshop Example item in the Project option. After clicking a project example, users need to first save it as another project, which requires filling in the project name and project path, then click “OK” to generate a new project. This new project is based on the project example with all parameters already configured, and can be used with the supporting evaluation board.
• If it is required to modify some parameters, users can modify them directly on the basis of the project example to quickly complete the project development.

Real-Time Monitoring Window Description

In order to help users understand the operating process of the evaluation board, the platform provides a real-time monitoring window, which can be opened through the Real-Time Monitoring button on the home page or through the Real-Time Monitoring item in the Tool menu. The following figures show the Real-Time Monitoring interface:

• This interface consists of the ① status area, ② information area, and ③ monitoring area, which are described in the following.

స్థితి ప్రాంతం

As shown in the figure, this area allows selecting the monitoring mode (currently only MPPT tracking mode), serial port, and baud rate, and importing data or exporting data through the Tool menu. When a serial port device is connected to or removed from the PC, the platform will automatically detect the serial port number and refresh the content in the serial port selection field. To communicate with the evaluation board, select the corresponding serial port, connect the USB side of the cable to the PC and the UART side to the evaluation board, select the same baud rate as the evaluation board (9600 by default), then open the serial port.

సమాచార ప్రాంతం

• To calculate the tracking efficiency, fill in the peak operating voltage (Um) and peak operating current (Im) of the PV board used, and click “OK”.
• Then the platform will automatically calculate the peak output power (Pm), open-circuit voltage (Uo), and short-circuit current (Is) of the PV board, and generate the P-V curve with a defaut fill factor of 0.68, as shown below:

పర్యవేక్షణ ప్రాంతం

• Before using the monitoring function, ensure that the evaluation board can normally communicate with the PC. Click “START” then the platform will periodically send the Get Parameter commands to the evaluation board based on the communication protocol, display the obtained parameter values on the left and display the current maximum power point tacking status with a small red dot in the measured P-V curve on the right.
• The horizontal coordinate represents the real-time input voltage and the vertical coordinate represents the real-time input power. Due to sampling errors, the data is for user reference only.
• The operating state on the left is represented by a double-byte data, and the meaning of each bit is shown in the table.
