| Abstract |
IGBT series-connected power switching circuit is presented. Voltage balance on IGBT’s is ensured by means of a simple auxiliary circuit applied directly on the high power inverter used in hard switching applications. Analysis in terms of dissipated energy, collector overvoltage and switching frequencies, comparing performances of a single high voltage IGBT (3300V) module and two series connected 1700V IGBTs is reported. An extended experimental analysis is also reported. Both analysis confirm the advantages in using two series connected IGBT in substitution of a single high voltage module in terms of power losses and switching performances. |
