Theoretical Analysis of Power Transfer Performance of Primary and Secondary Compensation Topology of Inductive Coupled Power Transfer System

Abstract:

Inductive coupled power transfer system is based on the principle of electromagnetic induction to transfer power from the primary side to the secondary side of a loosely coupled transformer, which can transfer electricity wirelessly. The loosely coupled transformer has large leakage inductance, which reduces the power transfer efficiency. In order to reduce the leakage inductance, a capacitance is used at the primary side and secondary side of a loosely coupled transformer, which can increase the power transfer efficiency. For four different compensation structures, this paper analyses the coupling coefficient and the secondary quality factor’s influence on the voltage gain, current gain and transfer efficiency, and also compares different compensation structures
