With the development of rail transit technology, auxiliary inverter which is as an important on-board power supply equipment faces more and more kinds of load equipment. Especially the nonlinear load (such as frequency conversion air conditioning) seriously affects the voltage quality of auxiliary power supply of trains. In the current research of auxiliary inverter control, the effect of 100% nonlinear load control is not good. In this paper, an improved resonant converter is introduced, which can suppress the specific subharmonics very well and has a relatively simple form. The model of the auxiliary inverter is established by MATLAB, and the control algorithm is verified.
