| Popis: | 85 The zero-current-switched quasi-resonant converter is derived from the combination of conventional PWM converters and resonant principles,by addinga LC resonant element to the switch of a PWM converter,so that in the switch high voltage and high current are not present at the same time.High power densityand high efficiency can be obtained with them,because the commutation tskes placeunder zero-current. In this report a Buck pulse-width-modulated zero-current-switched quasi- resonantconverter (Buck PWM ZCS QRC) operating at constant frequency is proposed and compared with the Buck frequency- modulated zero-current-switched quasi-resonant converter (Buck FM ZCS QRC).Finally,some selected experimental results are presented to verifythe proposed theory. |
