摘要：

A compact SiC converter having power densities about 9 W/cm(3) is designed and fabricated. It is confirmed that the converter operates in a thermally permissive range. The power loss of the module of the converter measured under motor operations is less than 50% of the similar-rating Si module loss. The shrink of the effective volume of DC-link capacitor is necessary to achieve the high power-density SiC converter, in addition to the decrease of the cooling system volume due to the loss reduction caused by SiC devices.
