Abstract

An analysis and experimental verification of a Class E voltage-driven resonant low di/dt rectifier are given. The circuit contains two resonant components: an inductor and a capacitor. Design equations are derived using Fourier series techniques. A prototype of the rectifier was built and tested at 500 kHz and an output voltage of 5 V. The theoretical and experimental results were in good agreement. The rectifier offers soft switching of the diode, decreasing noise and switching losses. However, the diode junction capacitance and the resonant components form a detrimental resonant circuit during the diode off state, causing ringing superimposed on the desirable waveforms.
