Abstract—Simulation of DC-DC converter side in SMPS system is discussed in this paper. A forward type soft switching DC-DC converter topology with neutral point inductor connected Auxiliary resonant snubber (NPC-ARS) circuit is presented in this paper for the switching mode power supply applications. Its circuit operation and its performance characteristics of the forward type soft switching DC-DC converter is described and the simulation results are presented.

Index Terms—Forward type DC-DC converter, Zero voltage soft switching, Zero current soft switching, neutral point inductor connected Auxiliary resonant snubber (NPC-ARS)circuit
