Abstract
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 regulated by a hysteretic control unit. The proposed rectifier can work in six operation modes by reconfiguring, and each output can be regulated in three modes. As a result, fine output regulation and large output-driving capability can be achieved. Designed in a 180-nm BCD process using standard 5-V devices, the dual-output rectifier provides two output voltages at 3 V and 5 V, and delivers a maximum power of 1.6 W. The peak post-layout simulated power conversion efficiency reaches 80.1% when both load currents are 0.2 A.
