DC-AC Conversion With Three Phase Sepic Inverter Based On The Boost Converter

Abstract

DC-AC conversion with three phase single ended primary inductance inverter and boost converter is a advanced design when comparing with conventional topologies .Here only used four-switches and three-phase SEPIC inverter .This pro- posed inverter is designed to reduce the fare, difficulty and switching losses .Converter offer a design for the inverter with the combination of single-ended primary-inductance with DC- DC converter which can be upgrade the phase voltage than traditional FSTP single ended primary inductance inverter . For boost up the output voltage inserting a boost converter (DC-DC) between input side and the four switch three phase single-ended primary-inductance inverter . Constant current control strategy is used with the proposed topology . Working principle , circuit diagram and simulation diagrams also introducing in this paper .
