“…Another significant drawback of the switch-mode operation is the EMI produced due to large di/dt and dv/dt. To overcome these short comings, new families of QRCs are introduced [1]- [2].Few research papers have been presented about the design and implementation of push-pull hard switched and Quasi-resonant converters [3]- [5].Push-pull converters is mainly used for medium and high power applications compared to half-bridge and full-bridge converter. It has wide duty ratio control and it can be used for multi-output applications with low output and input ripple current.…”

“…Como os conversores quase-ressonantes com modulação por largura de pulso (PWM-QRC) operam com freqüência de chaveamento constante, eles não apresentam o problema referente ao controle, encontrado nos QRCs , Barbi et al (1989). Entretanto, eles apresentam todas as outras desvantagens dos QRCs, limitando, assim, suas aplicações.…”

“…After, the QRC-PWM converters were proposed in [7]. These converters do not have control problems but they contain all the others disadvantages of the QRC.…”
