Voltage controllable power factor corrector based inductive coupling power transfer system

This paper proposed a novel inductive coupling power transfer (ICPT) topology to improve the power factor, output voltage regulation and efficiency. The proposed ICPT is mainly constructed by a voltage controllable power factor corrector (VC-PFC) and a LLC resonant circuit. Additionally, the series compensation and series-parallel compensation are used in the primary and the secondary sides of the coupling transformer to increase the coupling efficiency and the load range. Finally, the circuit simulation of the proposed ICPT is presented to verify the performance. Simulation results show that under the 10 mm coupling distance, the power factor correction and output voltage regulation can be achieved at the same time.
