Abstract

This paper presents an LLC series resonant high-frequency sinusoidal power supplier for contactless power transmission system utilizing the magnetizing inductance and the leakage inductance of contactless coupled transformer. The design of system's parameters is under 2mm air gap of contactless coupled transformer and utilizes microchip dsPIC30F4011 to track resonance tank voltage and current phase in order to maintain operation of circuit resonant frequency to ensure that circuit can provide maximum power output for various loads. Finally, a 1kW prototype is designed and implemented to access the performance of the proposed LLC series resonant high-frequency sinusoidal power supplier. The proposed circuit also compares with the traditional frequency fixed high-frequency sinusoidal power supplier. The experimental result shows that the proposed circuit can provide maximum power output for various loads and the efficiency is about 95%.
