A push-pull DC/DC converter was designed and manufactured using the PWM controller SG3524. The output voltage can be adjusted between 30 and 36 V, and the system efficiency can reach 92%. The entire converter is controlled by the C8051F020 microcontroller, which can display the input and output voltage, current and system efficiency, and can preset and step the output voltage. It can also realize over-current protection and over-voltage and under-voltage indication, completing all the requirements of the basic part and the development part.
