Abstract

As an important part of EMU (Electric Multiple Units), the auxiliary power supply system plays an important role in the normal operation of the vehicle. In order to improve the reliability of the auxiliary power supply system, this paper analyses the harmonics of the auxiliary inverter under nonlinear load and suggests that the 6th harmonic voltage components in the DQ synchronous rotating coordinate system can be controlled to achieve the simultaneous control of the 5th and 7th harmonic voltage components in the three-phase static coordinate system. The instantaneous voltage PIR (Proportion Integral Resonance) closed loop control method in DQ synchronous rotating coordinate system is researched to eliminate the voltage aberration caused by harmonics and ensure the quality of output voltage. Finally, the simulation results show that the design has achieved the desired objectives.
