A Novel Soft Switching Inverter for BLDCM EV Propulsion System

摘要：

A novel Zero Voltage Transition (ZVT) parallel resonant DC link Voltage Source Inverter (VSI) is proposed for Brushless DC Machine (BLDCM) Electric Vehicle (EV) propulsion system. The presented soft-switching inverter is constructed from the conventional one by simply augmenting auxiliary resonant DC link, and the soft switching is easily achieved by suitable controlling of the auxiliary switch. The Zero Voltage Switching (ZVS) operation for all switching devices in inverter has been achieved both for motoring and braking state. The DC link voltage is clamped to power voltage. Control of resonance is based on time sequence without testing any current or voltage, so Pulse Width Modulation (PWM) control is simple. The operation principle and control scheme of inverter are analyzed. Computer simulation results reveal good performance.
