摘要： A transmitter end includes a transmitter coil. The transmitter end further includes a transmitter end control system and N energy management modules, where N is an integer greater than 1. Input ends of the N energy management modules are electrically connected to a power grid, and output ends of the N energy management modules are electrically connected to the transmitter coil. Each energy management module includes an AC-DC circuit, an inverter circuit, and a transformer. The transmitter end control system is electrically connected to the inverter circuits in the N energy management modules, and is configured to output synchronous phase shift control signals with a fixed duty cycle, to drive the inverter circuits to work synchronously. The energy management module may be used in the transmitter end, and form a smallest module.

摘要： In a wireless charging transmitter, an output end of an inverter is connected to a transmitter LCC network; an output end of the transmitter LCC network is connected to a transmit coil; and a switch circuit is connected to the transmitter LCC network. The receiver includes a receiver LCC network. When a real part of a first output impedance of the inverter is greater than a real part of a second output impedance of the inverter, a transmitter controller controls the switch circuit to act, so that the wireless charging system works in a double-sided LCC network. When the real part of the first output impedance is less than or equal to the real part of the second output impedance, the transmitter controller controls the switch circuit to act, so that the wireless charging system works in a single-sided LCC network.
