    • A power conversion system for converting between electric and motive power may be utilized either in a generating mode to generate electric power from motive power supplied by a prime mover or in a starting mode wherein motive power is developed by the power conversion system from electrical power and is supplied through a torque converter to the prime mover to start same. The power conversion system includes a main generator, an exciter and a permanent magnet generator, or PMG, which together comprise a brushless alternator. When operated in the starting mode, power is supplied to the PMG to cause it to act as a motor and thereby drive a rotor which is common to the PMG, exciter and main generator. Once a predetermined operating condition of the generator is attained, the main generator is supplied power from a motor control to cause the generator to act as a synchronous motor and the power supply to the PMG is disconnected. The torque converter is then commanded to transfer motive power from the generator to the prime mover to start same.

    • A method and apparatus for controlling switches in an n-phase static inverter of the bridge type is disclosed wherein the inverter includes n pairs of switches connected across two DC voltages, with a phase output being developed at the junction between switches of each pair. In such an inverter, at any particular time, n.sub.1 phase outputs are connected to one of the DC voltages while n.sub.2 phase outputs are connected to the other DC voltage, where n.sub.1 .ltoreq.n.sub.2 and n.sub.1 +n.sub.2 =n. The n.sub.1 phase outputs are identified by logic circuitry and the switches associated with such phase outputs are operated during times when a pulse width modulation waveform is in a low state so that all phase outputs are connected to the same DC voltage. The method and apparatus of the present invention reduces the number of switching occurrences to the minimum required to achieve defined applied voltage pulse width modulation. Further, the method and apparatus of the present invention does not result in the generation of regenerative currents, and hence various types of DC sources may be used and the DC bus filter may be reduced or eliminated.

    • A ripple reduction circuit for an inverter which converts DC power supplied on DC buses into AC power to drive a load includes a sensing transformer having a primary winding coupled to one of the buses by a switch so that the ripple on the DC bus is sensed. A periodic voltage is impressed across a secondary winding of the sensing transformer due to the sensed ripple and this periodic waveform is coupled to a secondary winding of an output inductor. A primary winding of the output inductor is connected between the output of the inverter and the load. The primary winding of the output inductor receives a first ripple component due to ripple on the DC bus and a second ripple component which opposes the first as a result of the periodic waveform in the secondary winding of the output inductor. The two ripple components substantially cancel one another and hence a low distortion power waveform is delivered to the load.
