Abstract
In the dynamic characteristics test circuit for high-voltage and high-power power electronic devices, the laminated busbar is the main connecting component. The stray inductance of the laminated busbar is one of the key factors that affect the accuracy of the dynamic characteristics. Therefore, a low stray inductance laminated busbar for series-parallel capacitors is proposed, from the perspective of reducing self inductance and increasing mutual inductance. Through finite element simulation, the result of extracting the stray inductance of the laminated busbar is 4.16nH. Compared with the most basic laminated busbar, this stray inductance is very small.
