【CW32】Wireless power transmitter (Class E amplifier)

Overview

The resonant frequency of the transmitter is about 600-650kHz, and it is planned to generate a square wave drive of 600kHz with a duty cycle of 50% through the microcontroller. The receiving end can receive electric energy by configuring a pair of inductors and capacitors with a resonant frequency of about 600kHz. After receiving, a relatively constant voltage can be obtained through the rectification and filtering link. Note that do not touch the resonant capacitors at the transmitter and receiver with your hands, otherwise you will be burned. When wiring, pay attention to minimizing the resonant loop and reducing parasitic inductance.
