Isolated Two Inductor Boost Converter Start-up and Steady State Operation with any Output Voltage

This paper shows, a DC/DC isolated two inductor boost converter, able to start and to operate in permanent regime output voltage from 0 V to 400 V. The characteristics of voltages and currents in the converter make from this topology suitable to be used in applications of high relation between the voltages of input and output as it is the case of the hybrid vehicles (VH). This converter has two auxiliary windings that make from this topology apt to operate with any output voltage without problems in current when the converter starts up. Analysis, design, construction and experimental results of a prototype of laboratory of 200 W appear in this paper.
