Turbine power unit for hybrid electric vehicle applications

摘要

A power generation system for a hybrid electric vehicle is disclosed. The system includes a fuel source, a turbogenerator coupled to the fuel source, and a power controller. The power controller is electrically coupled to the turbogenerator, and includes first and second power converters. The first power converter converts AC power from the turbogenerator to DC power on a DC bus, and the second power converter converts the DC power on the DC bus to an operating DC power on output lines. The power controller regulates the fuel to the turbogenerator, independent of DC voltage on the DC bus. The system further includes an electric motor, a drive control unit coupled between the output lines and the electric motor, and a traction battery. The traction battery is coupled across the output lines, and provides an additional source of current, upon demand, to the electric motor.
