Abstract
In this paper, a detailed analysis of zero current or zero voltage switching boost converter using a single switch is described. The proposed topology is capable of decreasing switching loss of IGBT device using soft switching technique. As a results, it can be reduced size and weight of passive elements. Based on the mode analysis, practical design considerations are presented. We confirm the converter topology, principle of operation and simulation results obtained from the PSIM software. The performance of the proposed converter is verified by with 1kW(400V, 2.5A) prototype circuit operated at 30kHz.
