Investigation of Busbar-Structure for High Power Converter

Conference paper
Part of the Lecture Notes in Electrical Engineering book series (LNEE, volume 138)


In high power converter design, low-inductance busbar connecting DC capacitors and power devices is main concern to improve the quality of the whole power electronics system. This paper analyzes and designs a busbar structure in detail for prototype of the high-speed railway traction converter. The method of partial element equivalent circuit and the Q3D software were used to extract the stray inductance. A hollow-shaped structure is proposed with lower inductance than the initial U-shaped structure. The simulation results are given to illustrate the effectiveness.
