Abstract
This paper presents the performance analysis of high frequency parallel quasi-resonant converter for domestic induction heating application as well as industrial application. The power semiconductor switch like IGBT is incorporated in this high frequency converter. Parallel Quasi-resonant topology is selected to provide ZVS and ZCS operation during switching conditions to reduce switching losses. Here, IGBT provides better efficiency and faster switching technique. In the proposed topology, a diode is connected across the IGBT ensuring the ZVS operation during turn-ON that enhances the possibility of less turn-ON loss. On the other hand, the switching frequency nearly equal to the resonant frequency ensures the ZCS operation of the IGBT during turn-OFF, which also ensures a reduction of turn-OFF loss. As a result, the performance of the induction heating system gets improved. The proposed scheme is analyzed using PSIM software environment.
