Abstract:
1. An electric power generating system comprising: a plurality of variable power sources including at least one source of DC power and at least one source of AC power; upstream converters for converting power supplied by said plurality of power sources to a common source of power communicated to a common collector bus; a power grid for supplying three-phase power to components requiring three-phase power, and downstream on said common collector bus; downstream converters for providing said three phases of power to said power grid from said common collector bus; said common collector bus being a high voltage DC bus; a DC link inverter being positioned intermediate said common collector bus and said downstream converters, and said DC link inverter providing power to motor driven loads; said downstream converters being DC to AC converters with modulation to change DC power from said common collector bus to a phase of AC power for delivery to said three-phase power grid; and said converters including a high frequency converter, a transformer, and a single pole bi-directional switch, and there are at least 3 of said converters to provide 3 phases of AC power.
