ABSTRACT:
An AC exciter and a main AC generator are mounted on a common rotating shaft of an engine, and a power rectifier and a power inverter are connected in series to the output of the main AC generator. In starter mode, an external AC power source is connected by a switch to the input of the power rectifier, and the output of the power inverter is applied to an armature winding of the main AC generator to drive it as a nocommutator motor to start the engine. A permanent magnet AC generator is also mounted on the common shaft of the engine to provide DC excitation to the AC exciter after converting the output of the permanent magnet AC generator into DC current, and the output of the permanent magnet AC generator is further utilized to detect the rotational speed of the engine to control the switch.
