This novel converter proposes a Multiple Input and Multiple Output (MIMO) 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 electronic switches, for AC-DC and AC-AC conversions thyristors are preferred, whereas DC-DC and DC-AC operations require both turn-on and turn-off control so that transistor (IGBT) is the most suitable switch. The proposed converter is highly recommended for multiple source and multiple output operations, but it can perform one conversion at a time. Power rating of the converter can be up to kilowatts during DC-DC and DC-AC conversions process and AC-AC and AC-DC conversions rating may extend up to megawatts. Simulation model of the MIMO converter is examined in the MATLAB simulink model and the same verified in the real-time test bench model. 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 for 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 a 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.

用于通用电源转换操作的多输入多输出转换器

这种新颖的转换器提出了一种多输入多输出 (MIMO) 功率转换方法，用于 AC-DC、DC-DC、AC-AC 和 DC-AC 转换中的升压和降压过程。这种多功能转换器是使用电力电子开关设计的，对于 AC-DC 和 AC-AC 转换，晶闸管是首选，而 DC-DC 和 DC-AC 操作需要开启和关闭控制，因此晶体管 (IGBT) 是最合适的开关。建议的转换器强烈推荐用于多源和多输出操作，但它可以一次执行一个转换。在 DC-DC 和 DC-AC 转换过程中，转换器的额定功率最高可达千瓦，而 AC-AC 和 AC-DC 转换的额定功率最高可达兆瓦。MIMO 转换器的仿真模型在 MATLAB simulink 模型中进行了检查，并在实时测试台模型中进行了验证。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。基于晶闸管的晶体管和两个基于二极管的晶体管的所有四种操作模式都用于确保开关操作。研究工作的新颖之处在于所有模式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。所提出的单级功率转换由于低开关损耗而具有更高的效率。
