| Abstract: | By selecting the appropriate control strategies,it can improve the waveform＇ s quality and dynamic performance of sine wave inverter output. Based on the analysis of the difference of the inverter control methods （drive way and the control of modulation ratio ）, by PID control, the analysis of the inverter output voltage characteristic will be experimentally demonstrated on a single-phase inverter power supply device with dsPIC as the core control device. The test results show that with the use of the control scheme, the sine wave inverter system has good steady-state accuracy and dynamic characteristics. |
