Solar Based Soft Switching Isolated Dc-Dc Converter to Generate Five Regulated Dc Output Voltages

Abstract

The aim of the paper is to extend a solar base soft switching inaccessible DC-DC converter for generating five multiple dc output voltages. The key problem of switched mode power converter operation is to produce EMI due to great do/dot and did/dot through the time of switch mode process. consequently, to realize high switching frequencies in converters, the switching losses and EMI emission are reduced if each controlled switch in the converter is turn-on or turn-off only when current passing through and or voltage across the switch is zero. The concept was to incorporate resonant tanks in the converters to create oscillatory voltage and/or current waveforms so that zero voltage switching (ZVS) or zero current switching (ZCS) conditions can be created for the power switches. The converter is composed of five outputs altogether. The first and third outputs are regulated through the duty cycle control of first two asymmetrical half bridge converters, while the second output is regulated through the phase shift of the first two asymmetrical half bridge converters A clogged loop and untie loop direct techniques of the five several dc outputs are explained for solar based system.
