本文提出了一种计算高效的 3D 仿真方法,用于 SiC 功率 MOSFET 的动态电热分析。该策略依赖于整个器件的电路表示,其中电热反馈是通过等效电气网络实现的,并且基本器件单元由新颖的行为模型描述,该模型考虑了关键物理参数的非直观温度依赖性。
This paper presents a computationally efficient 3-D simulation approach for the dynamic electrothermal analysis of SiC power MOSFETs. The strategy relies on a circuit representation of the whole device, where the electrothermal feedback is enabled through an equivalent electrical network, and the elementary device cell is described by a novel behavioral model accounting for the non-intuitive temperature dependences of key physical parameters.
