“…Moreover., they limit the voltage stress across the switches to 1.2'VS . It is worth noting that the large inductor L,, of the two mutually coupled inductors used in the proposed circuit is not included in the main path of the power flow, as is the case in the other circuits [5] and [6], to minimize losses. Hence, the size of Lr2 is quite reduced.…”

“…This paper gives a family of novel circuits for ZVS quasi-resonant DC/DC converters. The proposed circuits use two coupled inductors with capacitor for the resonant circuit [5]- [7] to achieve zero voltage switching for turning on and off the main active control switch S,, and zero current switching (ZCS) for turning on the auxiliary control switch S as well as ZVS for turning it off. These topologies have W O switches-the main active control switch S, to control the output voltage and the auxiliary control switch S for achieving ZVS of the converters.…”

This paper presents some novel synchronized quasi-resonant circuits for achieving soft-switching DC/DC boost and flyback converters. These topologies use coupled inductors with capacitor for resonating circuit to achieve zero voltage switching of the converters. The circuits have minimum voltage stress across the switches. Moreover, they have reduced commutation losses and increased switching frequency. The paper explains the principle of operation of the circuit and describes the analysis of each mode of operation for both boost as well as flyback converters. It also gives design criteria, derived from the mathematical analysis carried out, for achieving zero voltage switching under all loading conditions from no load to full load. The feasibility of the proposed circuits has been verified by PSPlCE simulation.

“…The proposed circuits use two coupled inductors with capacitor for the resonant circuit [5] to achieve zero voltage and zero current (ZC) switching for turning off the control switch and ZCS for turning it on. They have only one control switch for achieving ZVS as well as to control the output voltage of the converters.…”
