        In view of the requirements of variable frequency amplitude modulation of modern power supply, it is proposed to use PIC16F873 to generate SPWM wave to control IR2136 to trigger IGBT to generate PWM wave to act on the inverter to produce a standard sine waveform, thereby realizing variable frequency amplitude modulation. At the same time, the AD module is used to sample the inverter bridge output and filter it to realize the PI closed-loop control of the system. The simulation analysis is carried out through the SIMULINK component in MATLAB. The results show that this scheme has a fast dynamic response speed of output voltage, good precision control and real-time performance, small waveform distortion and high reliability.
