Abstract: The traditional proportional integral (PI) and proportional resonant (PR) of two kinds of control strategy is proposed in this paper on the control method of the inverter. Firstly, the two kinds of control strategy is particularly analyzed in theory, and then the Simulink modeling of single phase inverter is simulated. The results show that, the two controller that is used in the inverter control system, can realize the inverter output waveform controlled effectively, make nearly no phase shift voltage output, also played a very good role of suppression of harmonic.
