    Abstract: A switched AC to AC converter circuit comprises a rectifying circuit, which generates a rectified output signal from an alternating input voltage signal, and a switching circuit for controllably switching the polarity of the output from the rectifying circuit to generate a quasi-sine wave or a stepped wave output voltage signal. The switching circuit is included in the rectifying circuit to form a switched rectifier. The switched AC to AC converter controls the integral number of half input wave cycles comprising a half cycle of the quasi-sine wave output in order to maintain the frequency and root mean square (rms) voltage of the output signal between predetermined limits. The switched AC to AC converter further controls the shape of the output voltage wave output to provide instantaneous control over the maintenance of the rms output voltage.

    Abstract: An apparatus includes a vehicular electric power generation system comprising a variable speed internal combustion engine, a first variable speed electric power generator driven by the engine, a second variable speed electric power generator driven by the engine, a first inverter to receive electric power from the first generator a provide a first controlled electric output, a second inverter to receive electric power from the second generator and provide a second controlled electric output, and a controller coupled to the engine. The controller is responsive to variation in electrical loading of the first inverter and the second inverter and a degree of electrical load imbalance between the first inverter and second inverter to provide one or more engine control signals. The engine is responsive to the one more engine control signals to change rotational operating speed to adjust for the variation in electrical loading and the degree of electrical load imbalance.
