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.

A method for generating electrical power associated with a hybrid vehicle or electrically propelled vehicle, the method comprising:
- selecting at least one of a power generation mode and an operational mode;
- activating 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 distinct from the drive electrical path to the drive motor if the vehicle is stationary and in the power generation mode;
- inverting a direct voltage signal to an alternating current signal with a desired frequency in the power generation path;
- and
- increasing a voltage level of the alternating current signal to a desired voltage level.
