How do you connect a capacitor to a bus bar?
The most common and easiest connection method for a capacitor onto a bus bar is a screw or bolt on connection. Soldering or spot welding connection methods can also be used, but they greatly increase the cost and complexity of the design. In sum, the bus bar design starts along with the power electronics converter design.
Why does a bus bar have a high frequency capacitor?
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) .
