摘要： An advanced power switching apparatus that is suitable for use in spacecraft and provides miniaturization, weight reduction, and improved reliability of power switching and protection functions. The apparatus provides greatly increased functionality, and is capable of switching power, isolating faults, and limiting in-rush and fault currents. The apparatus comprises a plurality of power switching circuits. Each power switching circuit comprises a switched power input and a switched power output, a switching device coupling the switched power input to the switched power output, the switching device having a control input, and an integrated circuit coupled to the switching device control input, having an enable input receiving a signal indicating whether the switching device is to be on or off, an input sensing current flow through the switching device, and an input sensing voltage at the switched power output, the circuit operable to control the switching device based on the control input, current sensing input and voltage sensing input.
