The inductive power transfer (IPT) system is increased resonant compensation networks to improve transfer efficiency and reduced the volt-ampere (VA) rating of power supply. The parameters deviation of compensation networks is greatly effect on input and output characteristics in IPT system. This paper researched the sensitivity of compensation network parameters and inverter frequency deviation to zero phase angle (ZPA), constant current (CC) and constant voltage (CV) characteristics, realizing load-independent ZPA, CC and CV characteristics through the parameter design of LCC-LCC, LCC-S and S-SP compensation network. An inductive power transfer system was designed to verify the correctness and feasibility of theoretical analysis.
