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.

这种新颖的综合转换器 (CC) 为 AC-DC、DC-DC、AC-AC 和 DC-AC 转换中的升压和降压过程提出了多种电源转换方法。这种多功能转换器是通过使用电力电子开关设计的，对于 AC-DC 和 AC-AC 转换，首选晶闸管，而 DC-DC 和 DC-AC 操作需要导通和关断控制，因此晶体管 (IGBT) 是首选最合适的开关。所有阶段的转换都可以根据需要由数字控制器控制。所有四种转换都可以执行升压和降压过程，因此电感和电容值的设计非常重要。所有四种操作模式都使用基于 4 个晶闸管的晶体管和两个基于二极管的晶体管来确保开关操作。研究工作的新颖之处在于所有模式中的功率转换可以是双向的，也可以是单级过程，但在现有系统中的功率转换是单向过程。由于低开关损耗，建议的单级功率转换具有更高的效率。该转换器采用数学分析设计，在仿真级别进行测试，并在实时实验中进行验证。
