The laminated structure of the bus bar creates a high frequency capacitor that helps mitigate the noise propagation , , though this unintended filter is likely not enough to completely remove the issue. An unavoidable result of fast switching devices is the high frequency harmonics, termed Electromagnetic Interfer-ence (EMI) .
Planar busbars have played a significant role in reducing the parasitic/stray inductance in modern high power converters, which is caused by physical current path loop from the IGBT to DC capacitors.

As illustrated by Fig. 9, DC current distribution is improved by splitting the positive and negative terminals in three. This reduces ohmic losses and evenly spread the heat across the bus bar, which reduces the hot spots. Typically, the bus bar conductors are sized for a 30 C self-heating temperature.
