Abstract

See full text

A hybrid power system for an aircraft. The hybrid power system comprises a high-voltage DC (HVDC) bus and a generator-motor system configured to (1) selectively receive electric power from the HVDC bus to assist in providing propulsion and (2) provide electric power to the HVDC bus during regulated power extraction. An LPS generator/motor is coupled with an LPS shaft of an engine. An HPS generator/motor is coupled with an HPS shaft of the engine. A first AC/DC converter is connected to the LPS generator/motor and the HVDC bus. A second AC/DC converter is connected to the HPS generator/motor, the first AC/DC converter, and the HVDC bus. An electric motor is connected to the HVDC bus and configured to provide propulsion and/or electric power. Further, AC and DC distribution systems are connected to the HVDC bus. A control system is configured to selectively control connections to the HVDC bus.
