Abstract :
A model has been developed for a fully integrated three phase inverter, the ECN3067, for use in variable speed drives. A macromodel is used for the integrated bipolar transistor (IGBT) power devices and the complete inverter is modelled in PSpice. The model has been shown to give accurate predictions of on-state and switching characteristics. Loss predictions have been verified by calorimetric measurements to show the effects of switching frequency and modulation method. For low switching frequencies, optimising the IGBTS for low on-state drop can greatly reduce losses and extend power handling capacity.
