Paper title: LOW PEAK CURRENT CLASS E RESONANT FULL-WAVE LOW DV/DT RECTIFIER DRIVEN BY A VOLTAGE GENERATOR
Author(s): ŞERBAN BĪRCĂ GĂLĂŢEANU,
Abstract: Abstract - Full-wave rectifiers allow to halve the diode peak voltages (or currents), but
these values may still be high at duty factor values far from 0.5. A new class E resonant
full-wave rectifier is proposed and analyzed, whose peak diode current is equal to the
load current. Diode voltage slopes are ideally zero after switch-off only for duty factors
larger than 0.5. The circuit contains two rectifier diodes but a single LC circuit. All
major parasitic reactive elements are included in the rectifier topology. Basic
parameters of the circuit are derived as functions of the diodes' duty factor. This allows
the user to find the optimum component values for a given application.
Experimental waveforms and measurements agree with simulations and calculations.
