近年来，对于诸如碳化硅（SiC）和氮化镓（GaN）器件的下一代功率器件的开发已经进行了广泛的研究，并且已经实现了高速开关电路。在这种情况下，高速开关操作可能在电力电子电路中产生电磁噪声和浪涌电压。电路中的杂散电感和电容是噪声和浪涌电压的关键参数。因此，对逆变器直流侧电路的杂散电感和杂散电容进行设计和分析具有重要意义。本文提出了一种综合考虑母线电感和电容的叠层母线设计方法。设计过程的有效性进行了测试，使用降压转换器电路额定在400 V和70 A的SiC MOSFET和SiC二极管。
Extensive research has been undertaken in recent years for the development of the next generation of power devices, such as silicon carbide (SiC) and gallium nitride (GaN) devices, and high-speed switching circuits have been implemented. In such cases, high-speed switching operations may generate electromagnetic noise and a surge voltage in the power electronics circuits. Stray inductance and capacitance in the circuits are critical parameters of the noise and surge voltage. Therefore, it is important to design and analyze the stray inductance and capacitance of the direct current (DC)-side circuit of an inverter. This paper proposes a laminated bus bar design procedure in consideration of both the inductance and the capacitance of the bus bar. The effectiveness of the design procedure was tested using a buck converter circuit rated at 400 V and 70 A with an SiC MOSFET and SiC diode.
