Power supply circuit consists of four parts, including voltage and current sampling circuit, voltage and current control circuit, push-pull structure of the main circuit, and drive circuit. The test results show that when discharging, it can achieve 0 ~ 5 V adjustable output voltage, the maximum output current of 5 A. When charging, it can achieve a 0 ~ 2 A current control function. The power supply ′ s rise speed and descent speed response time is less than 50 micr |
