Influence of the HV DC Bus Impedance on the Current Ripple Distribution in Electric Vehicles

Abstract

Current harmonics generated by the main inverter of an Electric Vehicle (EV) are distributed over the High Voltage (HV) DC bus. The influence of DC bus changes, e.g., adding or modifying HV components is investigated and a method to model and analyzed the distribution of the current harmonics over the DC bus and its HV components is proposed.
