Abstract: In this paper, Integrated Boost Parallel Fly-back Converter (IBPFC) with continuous mode is presented. The bulk capacitor will supply the voltage to two transformers. The two transformers turns ratio 1:1 The main advantage of this converter is high reliability, high power transfer efficiency and step up gain. Using this topology current stress on switches is reduced due to parallel operation. The parallel fly-back convertor and boost convertor dividing a common switch Q1; the input voltage VCB will be the parallel fly-back converter (PFC) is from the output of the boost convertor. The operating modes of IBPFC has been presented. A 24V input, 50Vand 50V outputs and 100W DC-DC isolated converter with 100 KHz of switching frequency is modeled using MAT-LAB Software and Simulation results have been presented.

Keywords: Integrated Boost Parallel Fly-back Converter (IBPFC), Open Loop Control, Continuous Conduction mode (CCM).
Scope of the Article: Computer Architecture and VLSI
