RECEIVE END AND TRANSMIT END OF WIRELESS CHARGING SYSTEM, METHOD, ELECTRICAL TERMINAL, AND SYSTEM

Example wireless charging systems and methods are disclosed. One example system includes a receive end and a transmit end. The receive end includes a receive coil, a receive end compensation circuit, a rectifier, and a controller. The controller adjusts a phase difference between a first bridge arm and a second bridge arm of the rectifier, and adjusts a phase-shift angle between a bridge arm voltage of the rectifier and a fundamental component of an input current of the rectifier, so that zero-voltage switching is implemented for controllable switching transistors of the rectifier. An inductance compensation module may weaken a capacitive part of the equivalent impedance, and reduce reactive power of the wireless charging system.
