摘要
Class DE low dv/dt rectifiers realize high-frequency high-efficiency rectification and low-diode voltage stress which is no more than the output voltage. Half-wave Class DE low dv/dt rectifier, which is one of the Class DE rectifiers, realizes the common ground between the input port and the output port. In this paper, the half-wave Class DE low dv/dt rectifier is analyzed for any diode-ON-duty ratio. The equations of the waveforms, the input and output powers, the current and voltage transfer functions, the current and voltage stresses, the power-output capability, and the power conversion efficiencies are obtained. Moreover, the characteristics of the normalized output power, the normalized input resistance and capacitance, the current and voltage transfer functions, and the power-output capability are clarified as functions of the diode-ON-duty ratio. The performance has been confirmed with the circuit experiment and the simulation in steady state. In the experiment and the simulation, the characteristics of the output voltage and the power conversion efficiency against the amplitude of the input current, the operating frequency and the load resistance have been obtained. The experimental results well agreed with the simulation results.
