Abstract
Disclose is a wireless electric energy transmission system for realizing PFC through secondary side modulation. According to the system, on the basis of a traditional wireless charging system topology, a traditional PFC circuit is removed, a grid voltage is turned into a 100 Hz voltage through uncontrolled rectification to directly supply power to an inverter of a primary side of a wireless charging system; an active full-bridge rectifying structure is adopted at a secondary side, and the PFC function is achieved only through secondary side modulation, wherein under the situation that a phase shift angle α of the inverter of the primary side is given.
