POWER DISTRIBUTION SYSTEMS
First Claim
1. A power distribution system comprising:
- first and second distribution busbars;
each carrying a respective distribution voltage;
a common power supply system supplying power to the first and second distribution busbars;
a power converter connected to the first distribution busbar the power converter having ac terminals; and
a controller that uses feedback signals indicative of electrical quantities of the distribution voltages carried by the first and second distribution busbars to control the power converter to regulate electrical quantities at the ac terminals of the power convener in order to achieve desired electrical quantities of the distribution voltage carried by the second distribution busbar.

Abstract
In a marine power distribution and propulsion system with a medium voltage distribution busbar (MVAC1) and a low voltage distribution busbar (LVAC1) then a rectifier (SC) is controlled, optionally to provide active filtering and static compensation benefits. A common power supply system incorporating ac generators (G1-G4) supplies power to the medium and low voltage distribution busbars. The rectifier (SC) is connected to the medium voltage distribution busbar (MVAC1). A controller (Co) uses feedback signals indicative of electrical quantities of the distribution voltages carried by both the medium voltage and low voltage distribution busbars (MVAC1, LVAC1) to control the rectifier (SC) to regulate electrical quantities at the ac terminals of the rectifier (SC) in order to achieve desired electrical quantities of the distribution voltage carried by the low voltage distribution busbar (LVAC1).
