摘要：
To realize load-independent voltage/current output of wireless power transfer (WPT) system, the double-sided CLC compensation network was proposed. Two switches in secondary side are utilized to switch the working modes of WPT system between constant voltage (CV) and constant current (CC) output. To reduce the complexity of the wireless power transfer system, the class D amplifier and class D rectifier are used to design the WPT prototype. The double-sided CLC-compensated WPT system was analyzed thoroughly and the simulation for CV and CC modes was performed. The simulation results show that in CV working mode the output voltage of WPT system only increases by 4% with a load fluctuation of 600% and in CC working mode, the output current only changes by 2.7% with a load fluctuation of 722%, which validates the load-independent CV/CC output characteristic of the propsed WPT system.
