摘要： An integrated circuit is configured to be coupled to a current sensing element and a set resistor having a resistance Rset. The integrated circuit comprises a sense resistor having a resistance Rsense.

The integrated circuit also comprises a reference resistor having a resistance Rreference which is a fixed multiple of Rsense; and circuitry configured to produce an output current such that the value of the output current is proportional to a value of Rset and a fixed ratio between Rsense and Rreference.

摘要： A latch-control protection circuit applied in a power converter is provided. The protection circuit has a comparing circuit unit and a logic gate. The comparing circuit unit is utilized to selectively output a default signal or a comparing signal according to a state signal from the logic gate, wherein the default signal is utilized for latching the state signal and the comparing signal is corresponded to the power condition of the power converter. The logic gate generates the state signal according to the output signal of the comparing circuit unit and a system judging signal. The output signal may be the default signal or the comparing signal. The system judging signal indicates the condition of the power converter.

摘要： A directional fault location and isolation system for a three phase electric power circuit that identifies a faulted segment by determining the direction of the fault at multiple tap points in the electric power circuit. The directional fault controller, which may be a centralized controller or a number of peer-to-peer controllers located at the tap points, includes communication equipment for exchanging information with the monitoring equipment and the sectionalizing equipment at each sectionalizing control point, which includes the tap points and may also include the substations. The controller also includes processing equipment that determines the directionality of a fault on the power line at each current monitoring device, identifies a faulted line section by identifying a change in the directionality of the fault associated with the faulted line section, and operates one or more of the sectionalizing switches to isolate the faulted line section from the circuit.
