中压SiC变换器关键部件外绝缘设计与光学评估方法

Exposed metal or insulator to air interfaces widely exists in medium voltage SiC-based converters. To effectively address external insulation along such interfaces, a large insulation distance in the air is applied. However, such insulation tends to significantly impair converter power densities and performances. Targeting the external discharge free design approaches that reflect the relationship...
