Impact of DC-Power Connection on the Stray Inductance of Bridge Arm in High-Power Converters

Abstract:

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. There are several facts which affect the stray inductance of bridge arm. This paper mainly analyzed the influence of DC-power connection on the stray inductance. The Psim9.0 software were used to calculated the stray inductance. The conclusion is that DC-power connection should be put different side of DC capacitance because lower stray inductance can be obtained than that of the same side. The simulation results are given to illustrate the effectiveness.
