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AC对DC电源转换的普遍，最有效的技术，反之亦然。它们用于每个行业，从电动汽车（EV）充电器到可变速度电动机驱动器，供暖，通风和空调（HVAC）系统，等等，依此类推，依此类推，其中70％以上的生产能量通过利用这些设备传输和转换。该研究项目介绍了可扩展电力转换器技术的新概念。这种新方法可以整合增强的高功率密度和基于高效率混合宽带盖（WBG）的多级电源电子转换器配置，从而增加了灵活性，从而可以提高整体功率转换系统的功率评级和弹性。此外，适当的几个转换器的正确并行需要特殊的控制和调制技术，以消除或减轻逆变器之间的电流和平等功率共享。平行的逆变器的新型控制技术和调制方法，用于提供快速瞬态响应，平行的逆变器之间的相等功率共享，最大程度地减少循环电流，从而确保可靠，灵活和冗余控制。因此，可以总结该研究项目的目的如下。首先，将开发完全工业的高功率密度和高效率三相混合WBG的多级电源电子转换器电池（MPECC），其中包括所有的被动和主动组件，其体积密度高于4 kW/dm3且效率高于98.5％的功率密度高于4 kW/dm3。然后，将开发一个可扩展的模块化双向背对背多级转换器，其中包括MPECC的两种不同并行配置。
