ABSTRACT:
A multiple DC-to-AC inverter system, which is suitable for an electric or hybrid vehicle application, includes a plurality of inverters controlled by a single controller. One example embodiment includes four three-phase inverters driving one six-phase motor, where the output of the first inverter is coupled to the output of the fourth inverter and the output of the second inverter is coupled to the output of the third inverter. In response to the failure of an inverter, the drive signals to the inverter that is coupled to the faulty inverter are updated such that the partner inverter can remain active without being driven into an over-current condition.
