CLASS-E RESONANT LOW DI DT RECTIFIER

An analysis and experimental verification of a Class E voltage-driven resonant low di/dt rectifier are given. The circuit contains two reson ant components: an inductor and a capacitor. Design equations are deri ved using Fourier series techniques. A prototype of the rectifier was built and tested at 500 kHz and an output voltage of 5 V. The theoreti cal and experimental results were in good agreement. The rectifier off ers 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, causin g ringing superimposed on the desirable waveforms.
