Design of low inductive busbars for medium voltage Neutral Point Clamped (NPC) inverter is studied. In a hard-switched inverter the stray inductance causes various problems, such as over voltages, current unbalance, and possible resonance with DC-link capacitors. These problems lead to improper operation of the inverter and an increased level of electromagnetic interference (EMI). The laminated busbars are known to be a good solution for minimizing the stray inductance. It is important to… CONTINUE READING
