Abstract :
This paper presents a novel topological prototype of voltage source series quasi-resonant zero current soft-switching pulse frequency modulated DC-DC power converter circuit using IGBTs which incorporates a high-frequency flyback transformer link. Its steady-state operating principle is described on the basis of simulation analysis, along with the open loop controlled power regulation characteristics of the multi-functional coupled inductors linked DC-DC power converter operating under a principle of zero current soft switching commutation.
