Abstract

Single-phase inverter output AC220V/50Hz voltage for the EMU, power supply for the passenger room socket. Traditional single-phase inverter usually adopts voltage RMS control. When passengers use non-controlled rectified nonlinear load such as mobile phone and laptop charger, the output voltage waveform distortion of single-phase inverter is serious, and the low-frequency voltage harmonic content is high. In this paper, an optimization scheme of the control algorithm is proposed. The voltage and current double closed-loop + proportional integral quasi-resonant control method is adopted to improve the dynamic performance of the system and reduce the harmonic content of the low-frequency voltage. By setting up the hardware environment and comparing the voltage and current waveforms before and after the optimization of the control algorithm, the effectiveness of the algorithm is verified.
