Abstract:
A power generation system, comprising:a DC bus; a turbogenerator including a motor/generator and a turbine coupled to a common shaft, to generate AC power; a first power converter coupled to the turbogenerator and the DC bus, to convert the AC power to DC power on the DC bus; a second power converter coupled to the DC bus and for coupling to a load, said second power converter converting the DC power on the DC bus to an output power for applying to the load; a capacitor coupled to the DC bus to source power to and sink power from the DC bus, due to load changes, to stabilize a DC voltage on the DC bus; and a controller coupled to the turbogenerator and the first power converter, the controller regulating a speed of the turbine, independent of the DC voltage on the DC bus.
