| Abstract |
Busbar structure is commonly used in power electronics applications, due to its low inductance.
However, although its low impedance, the busbar geometry can sometimes lead to unbalanced current
in paralleled components (power switches, capacitors...). This paper starts with the best way to provide
an electrical equivalent scheme of this component. It will be shown that some coupled resistive effects
influence current sharing, and must be taken into account in the modeling: an original method is given
to account for this phenomenon in common circuit simulators. Some solutions to balance current with
modification of busbar geometry is presented This method is applied to an industrial busbar.
Experimental validation are brought, in frequency and time domain. |
