In this paper, a Class DE voltage driven low dv/dt rectifier is proposed and analyzed for the diode-on duty-cycle. The proposed Class DE voltage driven low dv/dt rectifier has the advantage of low diode-voltage stress and diodes that can satisfy soft switching. Consequently, the switching loss can be reduced considerably. Equations of diodes and capacitor waveforms are obtained at the diode-on duty cycle. Moreover, the following performance parameters are obtained and clarified as functions for the diodeon duty cycle and for omega CR: the initial phase angle of the input voltage, the voltage and current transfer functions, the normalized input resistance and capacitance, the normalized diode current stress, and the power-output capability. In addition, the circuit design is provided and a method for calculating the power-conversion efficiency is described. With a simulation and an experiment, we derived the output voltage and the power-conversion efficiency as a function of the amplitude of the input voltage, the load resistance, and the operation frequency. The experimental results accorded with the theoretical calculations and the simulation results.
