本文提出了一种考虑母线几何形状的开关波形优化设计方法。在此拟议程序中，评估三项--浪涌电压、阻尼振荡和开关损耗--以实现用户定义的设计目标，从而实现优化的开关波形。本研究的目标是使用宽带隙器件的高速开关的母线几何形状，因此，在功率转换器中的寄生参数被认为是。由于要实现最佳开关波形，需要讨论母线的频率特性，因此通过有限元分析母线的寄生参数，即电感、电容和交流电阻。实验是使用降压转换器电路进行的，额定电压为400 V和30 A。其结果是，浪涌电压，阻尼振荡和开关损耗，分别减少13.2%，49.7%和29.7%，相对于用户定义的设计目标，同时。
This article proposes an optimization design procedure for the switching waveform considering a bus bar geometry. In this proposed procedure, three items—the surge voltage, damped oscillation, and switching loss—are evaluated to achieve user-defined design objectives for realizing the optimized switching waveform. This study targets a bus bar geometry for high-speed switching using wide band-gap devices; thus, parasitic parameters in the power converter are considered. The parasitic parameters, which are the inductance, capacitance, and ac resistance, of the bus bar are analyzed by finite element analysis because it should be discussed the frequency characteristics for realizing the optimum switching waveform. The experimentation is performed using buck converter circuits, rated at 400 V and 30 A. As a result, the surge voltage, damped oscillation, and switching loss are, respectively, reduced 13.2%, 49.7%, and 29.7% with respect to user-defined design objectives, simultaneously.
