Abstract
An onboard power generation system for use on board a vehicle, such as a passenger car, includes a brushless doubly-fed generator. The generator has a rotor with rotor conductors and a stator with stator windings, the stator windings comprising first and second polyphase stator systems. The generator rotor is mechanically coupled to and driven by the vehicle engine with a driving force to produce an AC power output from the first polyphase stator system. The generation system has a rectifier which receives and rectifies the generator first polyphase stator system AC power output into DC power for delivery to a DC bus of the generator power system. A sensor senses a parameter of the AC power output received by the rectifier and produces a sensor signal in response thereto. A converter receives the sensor signal, and in response thereto, converts power received from an excitation power source into excitation power for the generator second polyphase stator system. The converter operates to produce a controlled flow of AC power output from the first polyphase stator system of the generator regardless of variations of the driving force of the vehicle engine. A method is also provided of…
