Efficiency And Reliability

Modern dc power supplies provide power factor correction but the classical two-stage approach, using hard-switched preregulators, has detrimental effects on efficiency and reliability, particularly for high power applications. With some circuit modifications and the addition of a few magnetic components, diodes and capacitors, we have turned a classical boost power factor corrector into a high efficiency soft-switched version. The proposed converter turns on its single switch with zero current and turns it off with zero voltage. In this paper we explain the proposed changes, we study the waveforms and equations and we verify them with an experimental prototype. We also show how the converter can be used for modular single- and three-phase high power applications.<br /><br />

Zero Voltage

The switched-mode power conversion technologies have evolved from the basic PWM converters to resonant converters, quasi-resonant converters, multi-resonant converters, and most recently, to soft-switching PWM converters. In this paper, several typical resonant techniques and several soft-switching PWM techniques are reviewed, and their merits and limitations are assessed. The resonant techniques reviewed include the quasi-resonant converters, multi-resonant converters, Class-E converters, and resonant dc link converters; and the soft-switching PWM techniques reviewed include the zero-voltage-switched (ZVS) quasi-square-wave converters, ZVS-PWM converters, zero-current-switched PWM converters, zero-voltage- transition PWM converters, and zero-current-transition PWM converters.
