Patent ID: 7038329

Claim:
An electrical power generating and utilizing system, comprising: a prime mover; a three-phase induction generator rotated by said prime mover and providing electric power on a three-phase bus; said three-phase bus having a load and also being connectable to a three-phase grid by a three-phase circuit breaker; said load including at least one induction motor; at least one first insulated gate bipolar transistor switched bridge converter providing three-phase power to said at least one induction motor; at least one second insulated gate bipolar transistor switched bridge converter connected to said bus and controlled to provide DC power to said at least one first switched bridge converter; and a controller responsive to voltage and current on said bus to control said at least one second switched bridge converter to provide said DC voltage to said at least one first switched bridge converter while increasing the power factor of the power on said bus and not distorting the waveform of electric power on said bus.
