DUAL WINDING ELECTRIC ACTUATOR FOR HYBRID SYSTEM

摘要

A hybrid vehicle includes a dual winding electrical actuator for actuating an actuated mechanism. The actuator includes a low voltage winding coupled to a low voltage electrical system, and a high voltage winding coupled to a high voltage electrical system. Both the low voltage winding and the high voltage winding are operable to generate a magnetic field. The actuator includes an electromagnetic stator core that is operable to react against the magnetic field from both the low voltage winding and the high voltage winding to produce a torque. The dual winding actuator may be used as a voltage converter to convert the voltage between the high voltage electrical system and the low voltage electrical system, thereby eliminating the need for a separate voltage converter.
