Abstract
By modeling the LC tank of a wireless receiver as an AC current source that serves as the input, the H-bridge built with four power transistors can be switched to work in 1X, ½X and 0X modes to realize rectification and constant-current and constant-voltage charging, thus resulting in a single-stage wireless charger; and for low charging current, a ½X - 0X single-stage charger only needs three power switches.
