These converters feature soft-commutation at zero-current (ZC) in the active switches. The new ZCS-PWM Boost and new ZCS-PWM Zeta converters, both based on the new ZCS-PWM soft-commutation cell proposed, are used as examples to illustrate the operation of the new family of converters.451-456engBipolar transistorsCircuit theoryEfficiencyElectric commutationElectric inductorsElectric potentialPulse width modulationSemiconductor diodesSemiconductor switchesSwitching circuitsInsulated gate bipolar transistorsReverse recovery effectsSoft commutation cellZero current switching convertersPower convertersTrabalho apresentado em evento10.1109/PESC.1999.789045Acesso aberto2-s2.0-00333100386427185658143370
