Parallel IGBT-bridge induction motor drive

This example demonstrates the implementation of an induction motor driven using two IGBT inverters connected in parallel through an interphase transformer. The DC-link is modeled as a big capacitor with voltage source and 2 choppers for over-voltage protection. A critical aspect of the parallel bridge induction motor drive of Figure 13 is the individual firing delay between parallel IGBT, which can cause huge current spikes in the interphase transformer [13]. The Advanced Time-Stamped Bridge model allows the variation of individual IGBT characteristics and the study of this effect in real-time.
