Abstract

Conventional differential resonant rectifiers, i.e., differential class E rectifiers are promising solutions for high-frequency rectification applications. However, they generally suffer from poor output regulation, which leads to the use of a post regulator. In this paper, a differential resonant rectifier that achieves single-stage power processing with direct output voltage regulation, is proposed. The regulation is attained by adjusting the phase-shift between the input current and the gate drive signal of the rectifiers. Moreover, the reactive components of the power circuit are designed such that a relatively constant AC voltage waveform is attained for different coupling and load conditions. This ensures zero-voltage-switching (ZVS) and good regulation of the rectifier over a wide load range. The steady-state analysis and feedback control design of the rectifier are discussed. A prototype is built and tested. Experimental results are provided to verify the features. © 2020 IEEE.
