Power electronic converters (PECs) are a prevalent and most efficient technology for AC to DC power conversion and vice versa. They are used in every industry, from electric vehicle (EV) chargers, to variable-speed motor drives, heating, ventilation, and air conditioning (HVAC) systems, and so on where more than 70% of the produced energy transferred and converted by utilizing these devices. This research project introduces new concept of scalable power electronic converters technology. This new approach allows for integrating enhanced high power density and high efficiency hybrid wide bandgap (WBG) based multilevel power electronic converter configurations adding to it the flexibility which permit to increase the power rating and resiliency of the overall power conversion system. Moreover, proper paralleling of several converters necessitates special control and modulation techniques to eliminate or mitigate circulating current and equal power sharing between inverters. Novel control techniques and modulation methods for paralleled inverters for providing fast transient response, equal power sharing between the paralleled inverters, minimizing circulating current, ensuring therefore reliable, flexible, and redundant control are required. Accordingly, the objective of this research project can be summarized as follows. First, a fully industrial high-power density and high efficiency three-phase hybrid WBG based multilevel power electronic converter cell (MPECC) including all passive and active components with volumetric power density higher than 4 kW/dm3 and efficiency higher than 98.5% will be developed. Then, a scalable modular bidirectional back-to-back multilevel converter comprising two different parallel configurations of MPECCs will be developed.

电力电子转换器 (PEC) 是一种流行且最高效的交流到直流电源转换技术，反之亦然。它们应用于各个行业，从电动汽车 (EV) 充电器到变速电机驱动、供暖、通风和空调 (HVAC) 系统等，其中 70% 以上的生产能量通过利用这些设备。该研究项目引入了可扩展电力电子转换器技术的新概念。这种新方法允许集成基于增强型高功率密度和高效率混合宽带隙 (WBG) 的多级电力电子转换器配置，增加了灵活性，从而提高了整个电力转换系统的额定功率和弹性。此外，多个转换器的正确并联需要特殊的控制和调制技术，以消除或减轻循环电流以及逆变器之间的均等功率共享。并联逆变器需要新颖的控制技术和调制方法，以提供快速瞬态响应、并联逆变器之间的平等功率分配、最小化循环电流，从而确保可靠、灵活和冗余的控制。因此，本研究项目的目标可概括如下。首先，基于多电平电力电子转换器单元（MPECC）的完全工业化高功率密度和高效率三相混合WBG，包括所有无源和有源组件，体积功率密度高于4 kW/dm3，效率高于98.5%发达。然后，将开发一种可扩展的模块化双向背靠背多电平转换器，其中包含两种不同的 MPECC 并行配置。
