一种用于电动汽车动力传动系应用的SiC-MOSFET复合升压转换器表现出22 kW/L的体积功率密度和20 kW/kg的重量功率密度。复合转换器架构由部分功率升压、降压和双有源桥模块组成，与传统的Si-IGBT升压转换器相比，CAFE平均损耗降低了60%，功率密度提高了280%，磁性元件体积减少了76%。这些增益是通过基于FEMM中模拟的FEM方法的综合损耗模型（包括SiC-MOSFET开关损耗和磁损耗）的优化来实现的。22 kW/L SiC-MOSFET复合变换器的实验结果表明，US 06驱动循环的平均效率为97.5%，CAFE平均效率为97.8%。
A SiC-MOSFET composite boost converter for an electric vehicle power train application exhibits a volumetric power density of 22 kW/L and gravimetric power density of 20 kW/kg. The composite converter architecture, which is composed of partial-power boost, buck, and dual active bridge modules, leads to a 60% reduction in CAFE average losses, to a 280% improvement in power density, and to a 76% reduction in magnetics volume compared to the conventional Si-IGBT boost converter. These gains were achieved with the help of optimization based on a comprehensive loss model including SiC-MOSFET switching loss and magnetic losses based on the FEM method simulated in FEMM. Experimental results for the 22 kW/L SiC-MOSFET composite converter project 97.5% average efficiency on US06 driving cycle and a CAFE average efficiency of 97.8%.
