The main electric equipment of air conditioning unit of EMU is analyzed, and the structural principle of auxiliary power supply system is introduced. Using the software MATLAB / SIMULINK successfully established the main circuit model. The simulation results show that the inrush current and voltage drop of the EMU busbar are reduced by 73.51% and 95.24%, respectively. The simulation results verify the necessity of starting the air conditioner unit in sequence.
