Active class E rectifier for wireless power transmission receiving end

The invention discloses an active class E rectifier for a wireless power transmission receiving end. The active E-type rectifier circuit main body comprises a coil, a resonant capacitor, an inductor connected in parallel with two ends of a resonant network, a diode, a small capacitor connected in parallel with the diode, and an adjusting circuit formed by a large capacitor and a switch tube. Compared with the output power regulation topology of a common full-bridge rectifier series DCDC converter, the structure has the advantages of fewer components, higher power density and lower cost. 本发明公开了一种用于无线电能传输接收端的有源E类整流器。该有源E类整流器电路主体包含一个线圈、一个谐振电容、一个并联在谐振网络两端的电感、一个二极管、一个并联与二极管的小电容、一个由大电容与开关管构成的调节电路。与常用的全桥整流器串联DC-DC变换器的输出功率调节拓扑相比，该结构元器件更少，功率密度更高且成本更低。
