A Constant Output Voltage Control Strategy of Inductively Coupled Power Transfer System for Rail Transit System

Abstract

The semibridgrless active rectifier for inductively coupled power transfer (ICPT) system is proposed and the energy injection control for the semibridgeless active rectifier to realize the constant output voltage in this paper. Theoretical analysis show that with the proposed control strategy, the output voltage can be regulated without communication between the primary side and secondary side. The zero voltage switching (ZVS) of the inverter can be realized. Finally, the simulation results are provided, the feasibility and the good dynamic performance of the proposed strategy are verified.
