Buck/Boost DC?DC Converter Topology with Soft Switching for PV Converter Stations

Dr. P. Sivaraman, R. Manivannan

Abstract: This paper deals with a buck/boost dcdc converter topologywith Soft Switching for PV converter stations. In power electronic switches, soft switching is a possible way of reducing losses. Soft switching refers to the operation of power electronic switches are zero-voltage switches (ZVS) or zero-current switches (ZCS). All the power electronic switching devices are below zero-current switching during turn-on and zero-voltage switching during turn-off. In the converter, the switches is active undergo zero-capacitive turn-on lossesunlike switches in other soft-switched topologies. The switches do not practice any over voltage/over current stress proportional to load as in resonant converters. A detailed analysis of the DC-DC converter is discussed and simulation results obtained are presented.

Keywords: Zero current switching ZCS, Zero voltage switching ZVS, PV panel, buck-boost converter, DC-DC converter
