Abstract
A power conversion system utilizes a brushless generator driven by a prime mover when operating in a generating mode and drives the prime mover when operating in a starting mode. The system includes an AC/DC power rectifier and an inverter coupled to the AC/DC power rectifier for developing at least one AC voltage. Contactors are provided for coupling, when in the generating mode, the generator to the rectifier input and the inverter output to an AC load during operation in the generating mode, and for coupling an external power source to the rectifier input and the inverter output to the generator during operation in the starting mode. Transformers are provided for adjusting system voltages so that the generator windings need not be modified to accomplish starting of the prime mover.
