A 13.56MHz Fully Integrated 91.8% Efficiency Single-Stage Dual-Output Regulating Voltage Doubler for Biomedical Wireless Power Transfer

Dual-output regulating rectifier is highly desired in wireless power transfer (WPT) for sub-100mW bioimplants. Such rectifiers perform voltage rectification and dual-output regulation simultaneously, thus avoiding post DC-DC conversions and cascaded power losses [1 –4]. However, the conventional dual-output structure suffers from a low voltage...

A 6.78 MHz Dual-output Reconfigurable Rectifier with Hysteretic Output Regulation for Wireless Power Transfer Systems

A 6.78 MHz dual-output reconfigurable rectifier for wireless power transfer is presented. The proposed rectifier integrates AC-DC rectification and DC-DC regulation into a single-stage topology, alleviating received power loss and reducing system volume cost. By adding a switch matrix after rectifying bridge, a dual output can be realized and...
