本文介绍了电机损耗和温度降低与高开关频率的SiC基逆变器的高速电机。我们开发了原型SiC逆变器与拟议的SiC栅极驱动器和定制的SiC功率模块。所提出的栅极驱动器可以在较高的开关频率下降低开关损耗和开关延迟时间。我们还开发了无反并联SBD的SiC功率模块，以减少开关时间，并使开关频率更高成为可能。本文给出了一些实验结果证实，原型SiC逆变器降低逆变器损耗相比，硅IGBT逆变器在相同的开关频率，并且原型SiC逆变器降低电机损耗和温度与较高的开关频率。
This paper presents motor loss and temperature reduction performed with high switching frequency SiC-Based inverter for high speed motor. We developed prototype SiC inverter with proposed SiC gate drivers and custom SiC power modules. The proposed gate driver can reduce switching losses and switching delay time for higher switching frequency. We also developed SiC power modules without anti-parallel SBDs to reduce switching time and make it possible to enhance switching frequency higher. This paper shows some experimental results confirmed that the prototype SiC inverter reduces inverter loss compare to Silicon IGBT inverter at the same switching frequency, and also the prototype SiC inverter reduces motor loss and temperature with higher switching frequency.
