A first circuit comprises: an RF power source for providing difference mode power to the multipole via the RF signal; at least one inductor for forming at least one resonant LC circuit with the multipole for providing voltage gain for the RF signal; and a transformer, comprising a secondary tap, the transformer connected in parallel to the RF power source and further connected to the at least one inductor such that the signals injected into the secondary tap are communicated to the at least one resonant LC circuit.

Abstract: A power distribution system that can be used in naval ships and submarines includes a first power generation system including at least one power source for supplying power to a first service distribution system that includes at least one dc distribution busbar for carrying a distribution voltage and a distribution current and at least one switchboard that includes protective switchgear with contacts. A zonal power distribution sub-system includes a zonal power supply unit for supplying power to at least one electrical load and a zonal energy store connected to the at least one switchboard of the first service distribution system for supplying power to the zonal power supply unit. The at least one power source is regulated according to a power source foldback and stabilizing characteristic and a power source starting characteristic. The at least one electrical load is regulated according to a load shedding and stabilizing characteristic.

Abstract: Methods and systems of providing power to a central processing unit (CPU) provide for enhanced surge protection and increased battery life. In one approach, an integrated circuit as a power output stage with an output node, and a voltage regulator coupled to the power output stage. The voltage regulator selectively switches the power output stage into a current ramp down mode based on detection of a voltage surge at the output node. The power output stage has an associated current ramp down rate. The CPU is coupled to the output node and a surge notification input of the power output stage, where the power output stage accelerates the current ramp down based on a notification signal from the CPU.

Abstract: A generator structure is provided for generating an AC power for a load. The generator structure includes a generator connectable to a load and an engine operatively connected to the generator for driving the same. A generator controller is operatively connected to the engine for controlling operation thereof and operatively connected to a generator for controlling the AC power generated thereby. A communications link connects the generator control to a network.

Abstract: An embodiment of the invention is a DC ladder bus having a first positive DC rail and a first negative DC rail defining a first DC bus rail for carrying DC power. A second positive DC rail and a second negative DC rail defined a second DC bus rail carrying DC power. A plurality of rungs are coupled across the first DC bus rail and the second DC bus rail. A generator is coupled to each rung. A plurality of disconnects are associated with each of the rungs to individually isolate each of the rungs from one of the first DC bus rail and the second DC bus rail.

Abstract: A device including a comparator (3) each input of which receives signals from an information transmission line (1, 2) through a capacitor (4, 5), is characterized in that devices for forced switching (6) are interposed between the information transmission lines (1, 2) and the inputs of the comparator (3), the output of the latter being connected to one input of an OR gate (7) whose other input receives a reinitialization signal from a protocol decoder and whose output is connected directly and through an inverter to the device for forced switching (6) in order to reinitialize the comparator when the latter is blocked in a dominant state following interference.
