ABSTRACT:
A circuit for use with an induction generator. The circuit is arranged to initiate operation of the induction generator as a motor to bring the system up to operating speed and subsequently to rearrange the system automatically to cause the induction generator to operate in a generating mode. The automatic reconnection is effected as an incident of the motor reaching a preselected speed. Determination of the preselected speed may be effected by voltage responsive means in one form of the invention, and by centrifugal switch in another form of the invention. The control is effected by suitably selectively connecting the phase winding of the generator. In the illustrated embodiment, a starting capacitor and a power factor correction capacitor are automatically connected at proper times in the operation.
