Recently, SiC power devices were developed to reduce the size and weight of the power converter circuit. This paper presents a three‐phase inverter structure for reducing imbalances in the switching loss among power modules connected parallel to one another and among the three phases. A proposed double‐sided structure achieved an imbalance of less than 2% in the experimental switching loss using SiC power modules. In addition, it is shown that the double‐sided structure realized stable switching behavior under four SiC power modules connected in parallel.

开发用于减少并联连接和三相之间的开关损耗不平衡的逆变器结构

最近，开发了SiC功率器件以减小功率转换器电路的尺寸和重量。本文提出了一种三相逆变器结构，用于减少彼此并联连接的电源模块之间以及三相之间的开关损耗不平衡。提出的双面结构使用SiC功率模块在实验开关损耗方面实现了小于2％的不平衡。此外，还表明，在四个并联的SiC电源模块下，双面结构实现了稳定的开关性能。
