Paper Title:
The Design of Single Phase AC Regulated Power Supply with PWM Chopping Control Compensation
  Abstract

In view of the large volume and complex control circuit of current AC regulated power supply, a unipolar AC regulated power supply with chopping control compensation is designed, and the calculation method of output filter parameter of chopping circuit is given. In the system, MCU of STC12C5A62AD with 8-bit A/D input and PWM output is adopted, by which not only simple structure and control but also fast dynamic response are get; DC voltage sampling technique is adopted, so sampling frequency is up to 12.8kHz, sampling precision is high too; PWM chopping frequency is 4kHz, so capacity of filter capacitor and inductors are small, and harmonic is little. Experiment results of prototype show that the system has high precision of output voltage and greater practical value.
