An unavoidable result of fast switching devices is the high frequency harmonics, termed Electromagnetic Interfer-ence (EMI) .
Power den-sity is also a major requirement where the physical space taken up by a laminated bus bar is typically smaller than wires. In addi-tion, the shape allows for tighter and improved use of the space. Overall, this makes bus bars a clear choice when designing a high power converter.
