9.2 A 91%-Efficiency Single-Stage Bipolar Quad-Output Regulating Rectifier with Event-Driven Output Power Enhancement via Coil-Reused DC-DC for Wireless Power Transfer
Abstract
A bipolar quad-output regulating rectifier for wireless power transfer (WPT) is presented. Using only five power switches, it provides four independently regulated bipolar outputs. A coil-reused DC-DC mode sustains operation under heavy-load conditions beyond the RX input power limit. The rectifier achieves up to 173 mW output power, 91% peak efficiency, and fast transient recovery.
