Prior power conversion system operable in generating and starting modes have utililzed brushless generators which are suitable for only certain applications. In order to overcome this problem, a power conversion system operable in generating and starting modes utilizes a switched reluctance motor/generator which is reliable and inexpensive and which can be used in a variety of environments.

A power conversion system operable in a generating mode to convert motive power supplied by a prime mover into electrical power and in a starting mode to convert electrical power supplied by a power source into motive power, comprising: a switched reluctance motor/generator having a motive power shaft coupled to the prime mover during operation in the generating mode and an electrical winding; a first electrical power converter coupled to the electrical winding; a second electrical power converter coupled to the first electrical power converter by a DC link; means for coupling a load bus to the second power converter during operation in the generating mode, and for coupling the power source to either of the first and second power converters during operation in the starting mode; and means coupled to the power converters for operating same whereby the motor/generator develops electrical power in the generating mode which is rectified by the first power converter to produce DC power, the DC power being converted by the second power converter into output power and whereby DC power is provided on the DC link during operation in the starting mode which is in turn used by the first power converter to cause the motor/generator to develop motive power.
