The auxiliary resonant commutated pole (ARCP) inverter is an attractive technology for electric vehicle traction inverter applications since it can eliminate most of the switching losses and improve the overall efficiency. However, the selection of resonant circuit elements significantly impacts the inverter’s performance. This paper proposes a resonant circuit element selection method that reduces current stress in the auxiliary resonant circuit of an ARCP inverter and helps to achieve a high efficiency. The current stress is reduced by 20.8% and 48.3% compared to previously reported methods and improves the overall efficiency between 0.6% to 9.5% depending on the load. Simulations were conducted using a 45kW, 3-phase, 700V system in LTspice and PLECS to validate the proposed method. The simulation outcomes indicate that the proposed approach is efficient and can be applied to the design and implementation of ARCP inverters. By carefully selecting the components in the auxiliary circuit, the proposed method enables achieving both reduced current stress and improved efficiency.
