无线电能传输系统的一种低成本最大效率跟踪方法

This paper presents a novel maximum efficiency point (MEP) tracking method for wireless power transfer (WPT) systems. It is proved that at the MEP for a typical system containing a boost converter on the receiving end, the derivative dD/dVin (Vin being the inverter's dc input and D being the duty cycle of the converter) is equal to or smaller than a constant β that is determined by system paramete...
