Abstract
A system and for generating power associated with a hybrid vehicle or electrically propelled vehicle comprises a mode selector for selecting at least one of an operational mode and a power generation mode. A controller activates one or more switches to disconnect an inverter output from a drive electrical path to a drive motor and to connect the inverter output to a power generation path if the vehicle is in the power generation mode. An inverter inverts a direct voltage signal to an alternating current signal with a desired frequency in the power generation path. A transformer increases a voltage level of the alternating current signal to a desired voltage level.
