Abstract: An offshore floating wind turbine apparatus provides a pair of spaced apart hull sections with a space between the hull sections. One or more gantries each connect to the hull sections. The one or more gantries are spaced apart and connected to the hull sections with pivotal or universal joint connections. A wind turbine tower has upper and lower end portions. The wind turbine tower has a lower end portion with a base that is mounted to one of the gantries. The tower upper end portion has a rotor, hub, nacelle, and blades. A mooring system preferably holds the hull sections on a desired offshore marine location.

Abstract: A high-power laser system includes a plurality of cascaded diode drivers, a pump source, and a laser element. The diode drivers are configured to generate a continuous driver signal. The pump source is configured to generate radiated energy in response to the continuous driver signal. The laser element is disposed downstream from the pump source and is configured to generate a laser beam in response to stimulation via the radiated energy. The high-power laser system further includes an electronic controller configured to output at least one driver signal that operates the plurality of diode drivers at a fixed frequency. The at least one driver signal operates a first cascade diode driver among the plurality of diode drivers 90 degrees out of phase with respect to a second cascade diode driver among the plurality of diode drivers.

Abstract: Methods and apparatus are provided for a current control circuit that forces current sharing among paralleled power converters. Each power converter has an associated current control circuit, which includes a current amplifier and a coupling circuit. The current amplifier outputs a feedback signal to a voltage regulation error amplifier when the power converter output current falls below a predetermined threshold level. The error amplifier causes an increase in the power converter output voltage, forcing an increase in output current. Therefore, each power converter in a paralleled arrangement is regulated to provide a minimum level of output current, based on a predetermined threshold value.
