A Two Input Two Output Step Up Type Transformerless DC-DC Converter

Abstract

A transformerless two input two output step up DC-DC converter is introduced in this paper. The main features of the presented converter are good efficiency, simultaneous power delivery from the connected energy sources, relatively lower voltage stress across the switching devices, unidirectional power flow etc. The given converter is constructive in the hybrid energy system as it incorporates two sources and supplies two different voltages at the load side. Various working states are explained with the help of supporting equations and equivalent circuits. The output voltage equations are deduced. Converter justification has been done by the help of experimental and simulation results. Different waveforms like voltages and currents of inductor, output voltages etc., obtained from both the experimental and simulation studies are included to underline the skillful function of the converter.
