Abstract

Switching transient processes of silicon carbide (SiC) devices induce several challenges, such as voltage and current overshoots, switching losses, $d v / d t$ , $d i / d t$ , and electromagnetic interference (EMI), threatening the safe and efficient operation of power electronic systems. Characterization of SiC modules is crucial to address these issues. This paper characterizes the dynamic and EMI performance of a state-of-the-art $1.2 kV / 100 A$ all-SiC module with the Easy-2B package from Fuji Electric. Using a double pulse test (DPT) platform, the dynamic characteristics are assessed across varying load conditions and gate resistances. Additionally, EMI characteristics of the module are evaluated in a semi-anechoic chamber. Results indicate significant impacts of gate drive parameters and load conditions on switching dynamic and EMI characteristics. These influences are further analyzed based on experimental results and theoretical analysis of the switching transient processes. Finally, the study identifies factors limiting switching speed improvements in SiC modules, including voltage and current overshoots, gate voltage oscillations, and EMI, offering valuable insights for improving device performance.

采用Easy-2B封装的1.2 kV/ 100a全sic模块的开关动态和电磁干扰特性

碳化硅（SiC）器件的开关瞬态过程引起了一些挑战，如电压和电流超调，开关损耗，dv/dt$ dv/dt$，di/dt$ di/dt$，以及电磁干扰（EMI），威胁着电力电子系统的安全高效运行。SiC模块的表征对于解决这些问题至关重要。本文描述了采用富士电机Easy-2B封装的最先进的1.2 kV / 100 a $1.2 \text{kV} / 100 \text{a}$全sic模块的动态和EMI性能。利用双脉冲测试（DPT）平台，评估了不同负载条件和栅极电阻下的动态特性。此外，在半消声室中对模块的电磁干扰特性进行了评估。结果表明，栅极驱动参数和负载条件对开关动态特性和电磁干扰特性有显著影响。根据实验结果和开关暂态过程的理论分析，进一步分析了这些影响。最后，该研究确定了限制SiC模块开关速度改进的因素，包括电压和电流过调、栅极电压振荡和EMI，为提高器件性能提供了有价值的见解。
