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 first and second bidirectional converter/inverter units, each of the bidirectional units being operable as either an AC to DC converter or a DC to AC inverter. A DC link couples the first and second bidirectional units. A transformer is connected to the second unit and the first unit is further connected to the armature windings, the transformer further being connected to the external power source. A control unit is connected to the first and second bidirectional units and causes the first bidirectional unit to operate as a converter and the second bidirectional unit to operate as an inverter when operating in the generating mode, and for causing the first bidirectional unit to operate as an inverter and the second bidirectional unit to operate as a converter when operating in the starting mode.
