Bidirectional DC-DC power converter
Set up the voltage and current closed loop, measure the voltage through resistor voltage division, and perform ADC acquisition.
Using LM358 as a voltage follower, LM358 can increase the input impedance,
It can reduce the interference of main topology on collection.
It has the characteristics of small ripple, wide input range and high conversion efficiency. The constant current and constant voltage parts all adopt PWM control principle.
Process, forming a closed loop to control the current or constant. The above section ensures that the system meets basic requirements,
Realizes constant current charging, constant voltage discharging, overvoltage protection functions, and has high conversion efficiency.
