Current sharing control demo

![WeChat picture_20230504144906.jpg]
# Description:
- Input voltage: DC 24V
- Output voltage: 0-24V adjustable
- Output current: There is no problem in outputting more than 10A (the diode SS54 selected here will heat up if the current exceeds about 3A, so it is necessary Choose a diode with a larger current)
- MCU uses national technology N32G031F8S7
- Half-bridge driver IC uses EG2104 instead of IR2104
- Current detection IC uses CC6903SO-10A instead of CC6904SO-10A
- 12V auxiliary power supply: Use EUP3458VIR1 power supply chip
- 3.3V auxiliary power supply : Use LM1117MP-3.3/NOPB LDO chip
- I roughly selected the device parameters inside, please choose the device with appropriate parameters according to your own needs

# Control idea:
![image.png] - The main BUCK loop uses PID for constant voltage and constant Flow control
- When dual BUCK circuits output at the same time, the output current of the slave BUCK circuit follows the current regulation of the main BUCK circuit
- When the output power is not large, a single output can be used, and there is no need for dual output at the same time
- A serial port is led out for serial communication , modify the output voltage and current
# Multiple current balancing boards in parallel (expanded)
![image.png] - Lead out the power supply, auxiliary power supply, and serial port pin header interface to facilitate the connection of multiple current balancing boards. For example, place one PCB on top and another on the bottom, and connect them directly through the pin header to form a stacked structure.
- Connect multiple current balancing boards in parallel, and transfer the current data of the main current balancing board to the slave current balancing board through the serial port to achieve the parallel output of more BUCK circuits and increase the output power.
