ABSTRACT:
An integrated traction inverter and battery charger apparatus which is capable of operating in either drive or charge modes. The apparatus integrates the components of a prior art three-phase inverter with an AC line-powered prior art DC source charger in a manner which recognizes that an input capacitor and certain components of a three-phase bridge inverter are capable of performing dual functions and thus can be active in both modes. Therefore, in the integration of the prior art devices some of the components are eliminated allowing savings in cost and weight of, and space required by, the components of the integrated inverter/charger apparatus.
