Resonant harmonic reaction in twin- and quadruplet-diode rectifiers

Abstract

This study answers the basic question of whether a simple lumped-constant (LC) resonator works for harmonic reactions in diode rectifiers. To explore how the LC resonator generally reacts to harmonic waves, we present three typical diode rectifier topologies: double-voltage, double-current, and full-bridge. Through an algebraic circuit analysis of the diode’s time-domain switching operation, we find that the second- and higher-order harmonic waves generated by the diodes are fully reflected by the LC resonator, return to the diodes, and are recycled for effective dc power generation. This outcome offers a simpler alternative solution for high-efficiency RF rectification than usual class-E and -F implementation.
