Abstract
The present invention provides an accessory drive system for a hybrid vehicle. The accessory drive system includes an inverter operatively connected to a direct current battery. The inverter is configured to convert the direct current from the battery into three-phase alternating current. The accessory drive system also includes a transmission having a first motor/generator operable to drive the hybrid vehicle. The first motor/generator is a Y-connected three phase motor/generator that defines a first neutral point. A second motor/generator is connected to an accessory and to the first neutral point. Output from the battery is transferable through the first neutral point to the second motor/generator such that the accessory is driven at a selectable rate.
