摘要：

In this paper, one single leg T-type converter with full silicon carbide (SiC) half-bridge power modules and hybrid power modules combined silicon carbide (SiC) with silicon (Si) power module, are designed and investigated. Firstly, the switching characteristics of Cree SiC device CAS300M12BM2 and Semikron SiC device SKM350MB120SCH17 single-leg T-Type converters are compared with double pulse testing (DPT). Then, to further investigate the performance, the hybrid power modules of the single leg T-type converter with Cree SiC device CAS300M12BM2 and Semikron Si device SKM300GM12T4 are built, which can increases the power density, compared to the full SiC devices T-type converter. To suppress the ringing of the middle leg switching device, the resistor-capacitor (RC) snubber are designed and demonstrated with DPT. Finally, the function testing of the hybrid single leg T-type converter are experimentally verified.
