Design and Implementation of Comprehensive Converter

This novel Comprehensive Converter (CC) proposes multiple power conversion approach for step-up and step-down processes in AC-DC, DC-DC, AC-AC and DC-AC conversions. This versatile converter is designed by using power electronics switches, for AC-DC & AC-AC conversions thyristors are preferred, whereas DC-DC & DC-AC operations require both turn-On and turn-Off control so transistors (IGBT) is the most suitable switch. Conversion in all the stages can be controlled by a digital controller according to the requirement. All four conversions can perform step-up as well as step-down process, so design of inductor and capacitor values are very much important. All four modes of operations 4 thyristor based transistors and two diode based transistors are used to ensure switching operations. Novelty of the research work is conversion of power in all the modes can be bidirectional and also in single stage process, but in the existing systems of power conversions is an unidirectional process. Proposed single stage power conversion has more efficiency because of low switching losses. This proposed converter was designed by using mathematical analysis, tested at simulation level and verified in the real time experiment.
