Time reversal duality and the synthesis of a double class E DC-DC converter

The principle of time reversal duality is introduced and applied to DC-DC power converters. Elementary inverters and rectifiers are time reversal duals of each other. When coupled together by a reactive matching network, a DC-DC converter whose properties are determined largely by the matching network is formed. This approach has application in the analysis and syntheses of PWM (pulse width modulation), resonant, quasi-resonant, and multiresonant converters. It is used here to synthesize a Cuk converter, and a double class E DC-DC power converter in which the switch and diode both operate in class E. The converter is ideally lossless for any DC load including open and short circuits.<>
