An Analog Switching (Non PWM) High Power Inverter for EMI Suppression in On-Line Electric Vehicle (OLEV)

摘要

In this paper we introduce the on-line electric vehicle (OLEV) system. We also introduce the non-contact power transfer concept of OLEV and EMI issues that could occur to the power rail of the system. To suppress EMI at the power rail of OLEV system, we propose analog switching concept and analog switching full-bridge inverter, instead of conventional PWM switching inverter. The proposed method is verified by simulation, and it shows that analog switching inverter has better effect on suppressing EMI than conventional switching inverters.
