    摘要: An inrush current limiter for electronic fuses detects the type of load connected to the electronic fuse at ignition. By detecting the type of load, the limiter prevents a large peak current from flowing through the fuse. When a short circuit occurs, the limiter ensures that the electronic fuse only operates once in linear mode.

    摘要: Embodiments of the present invention provide a high voltage direct current soft-start circuit in which a first end of a first switch is connected to a negative electrode of a high voltage direct current, a first end of a second switch is connected to the negative electrode of the high voltage direct current, and a drive control unit is connected separately to the first switch, the second switch, and a load, where a first part of a connector is connected to the drive control unit, and upon power-on, the first part of the connector communicates with a second part of the connector, to trigger the drive control unit to drive the first switch to turn on; and the drive control unit delays a preset time after driving the first switch to turn on, drives the second switch to turn on, and drives the load to start after the second switch is turned on. In the embodiments of the present invention, a connector can be inserted and disconnected without generating an electric arc, thereby avoiding generating an arc discharge, and implementing arc-free hot plugging of a high voltage direct current power supply apparatus; moreover, no improvement needs to be made to the connector itself, so that the connector has a relatively small size.

    摘要: A novel system is offered for supplying power from an input node to a load coupled to an output node. The system may have multiple switches (Q1, Q2) coupled between the input node and the output node. One or more limiting circuits (304-311) may be configured for controlling the switches so as to limit outputs of the switches. For example, the limiting circuits may limit current through the respective switches. One or more timers (312, 412, 414) may set a delay period for indicating a fault condition after the limiting is initiated.

    摘要: Active inrush current control includes activating (1001) a load (305), the activating causing inrush current to flow, switching (1002) a semiconductor switching device (301) to a current limiting state in response to the inrush current flow, the current limiting state being one of at least three states of the semiconductor switching device (301) and the current limiting state dissipating the inrush current, and switching (1003) the semiconductor device (301) to a full current flow state in response to the dissipating, the full current flow state not inhibiting current flow.

    摘要: A semiconductor device 1 includes: an output transistor MN1; and a current detection section 2. The output transistor controls electric power supply from an electric power source to a load 12. The current detection section detects a current flowing through the output transistor. The current detection section has a current detection characteristic in which a current detection value has approximately linier and negative dependence on a drain-source voltage of the output transistor.
