Abstract
This paper presents a topology to cost-effectively integrate the advantages of wide bandgap semiconductors into the application field of inverters for BLDC motors. A novel approach exhibits an increase in efficiency at comparable costs and power density compared to conventional approaches. It is particularly suitable for small electric vehicles for urban areas. The investigation is based on a comparison between the proposed hybrid buck-type topology and a conventional B6 circuit. A demonstrator is used for verification and performance analysis.
