In this paper, a comparative analysis of the topology of the metro auxiliary inverter system was carried out, and the two level metro auxiliary inverter was studied, This system was applied a double closed-loop control strategy, which guarantee the stability of the AC output side voltage and meet the needs of different loads. On this basis, the MATLAB simulation model was built, and the simulation results show that the auxiliary inverter output meets performance demands, and the feasibility of the scheme is verified.
