Abstract

In this paper, a novel boost-based quasi resonant DC-DC converter is proposed, featuring low component count. The proposed topology also achieves a high voltage gain with a wide output power range while profiting from a simple structure. An inductor is introduced in the termination of the circuit that takes part in the resonant process instead of creating a voltage spike across the switch during the switching time. Moreover, the circuit achieves soft switching (ZVS-ZCS in turn on/off transitions of the switch), leading to reduced losses and improved efficiency. Working with a suitable switching frequency is a contributory factor in reducing the size of passive components. The operational principles and a comprehensive steady state analysis in the continuous conduction mode (CCM) as well as design considerations for the proposed converter are discussed in details.
