摘要：研發了一種結勢壘肖特基（JBS）二極管，在3kV電壓下，具有低正向電壓和低漏電流特性。用Si-IGBTs和SiC-JBS二極管搭建了標準3kV/200A混合模塊。通過采用混合模塊和高速驅動電路，我們試圖降低反向恢復損耗及開通功率損耗。同時，我們估算變流器和逆變器的總能量損耗減小到原來的32.4%。另外，混合模塊能成功地驅動列車的感應電動機。
敘詞：高速驅動電路 變流器 SiC Abstract：Abstract: A JBS diode is developed with features of low forward voltage and low leakage current under the voltage of 3kV. A starndardised 3kV/200A mixed modular is constructed using Si-IGBTs and SiC-JBS diodes. By adopting mixed modular and high-speed drive circuit, we try to lower the backward recovery loss and cut-over power loss. In the meantime, it is estimated that the total power loss of convertor and inverter can be lowered to 32.4 percent of the original situation. In additon, mixed modular can drive the induction motor of a train successfully. Keyword：Keywords: High-speed driver circuit, Convertor, SiC
