Abstract
A generator starting system utilizes a portable universal battery pack to start an internal combustion engine of the generator. The system is adapted to utilize any one of a plurality of universal battery packs having outputs of varying voltage. The generator can include a permanent magnet generator having first and second sets of windings. One set of windings generates AC power. The second set of windings is used to drive the PMG as an electric motor using power from the universal battery pack. In an embodiment, the system includes a brushless DC controller that electronically commutates the second set of windings to drive the PMG as a brushless DC motor.
