N2 - The active rectifier technology is commonly adopted in wireless power transfer system (WPTS) for improving efficiency. However, active rectifier requires complicated phase-locked method to provide synchronization signal for pickup side controller. In this paper, A new relatively simple and reliable phase-locked method has been proposed for WPTS based on the semi-bridgeless active rectifier (S-BAR) with the double-sided LCC compensation, which doesn't need to detect the current in the resonant. Moreover, an improved control strategy for semi-bridgeless active rectifier (S-BAR) is also proposed based the phase locked method, which can regulate the output power of the system and eliminate the conduction loss of MOSFET-based body diode. Furthermore, the inverter primary side switches the operating mode according to the amount of output power. Therefore, a large amount of reactive power in the system can be avoided in light load. Finally, a 200W experimental prototype is built to verify the validity of the proposed method.
