Voltage Regulating Strategy of a New LCC/S+L Inductive Power Transfer System

Abstract In the voltage control of inductive power transfer (IPT) system, a cascaded DC-DC converter is normally adopted which reduces density. However, wireless communication between transmitter and receiver may lead to delay as well instability. This paper proposes new LCC/S+L resonance topology for IPT can realize single-stage regulation on receiving side with both buck boost capability. Based fundamental wave analysis method, this analyzes working principle resonant topology. Then strategy phase shift angle bridges within obtained by ends series inductor load vector. It verified simulation that proposed achieve output 300-500 V constant 375 input DC voltage.
