摘要： A solid state circuit breaker is disclosed for use in connection with a voltage bus, the voltage bus supplying electrical current to a load. The solid state circuit breaker includes a current controller for controlling the magnitude of current supplied by the voltage bus. A first current sensor senses the magnitude of the electrical current supplied by the voltage bus, the first current sensor having an output in communication with the current controller. An inductor is included within the first current sensor, the inductor providing a back electromotive force on the voltage bus. The back electromotive force is proportional to the rate of change of current flowing through the voltage bus.

摘要： A start-up circuit for a high voltage power distribution circuit includes a transistor, a current source which generates ramped current, an operational amplifier which is connected between the current source and the transistor and controls the transistor, a capacitor which is fed the generated ramped current from the current source and is charged by the generated ramped current, the capacitor being connected to the non-inverting input of the operational amplifier, and a feedback capacitor connected from the transistor output to the non-inverting input of the operational amplifier, which is fed the generated ramped current from the capacitor and is discharged. The transistor is fully enabled when the feedback capacitor is fully discharged.

摘要： A control circuit is provided which includes a pre-charge circuit connected in parallel with a solid state switching device of, for example, a power distribution network. The pre-charge circuit pre-charges a load capacitance at a load side of the switching device prior to activation of the switching device. The pre-charge circuit includes a threshold waveform generation circuit and an over-current detect circuit. The threshold waveform generation circuit synthesizes a maximum acceptable charging waveform for the pre-charge circuit in charging the load capacitance, and the over-current detect circuit signals an over-current fault condition upon a charging current through the pre-charge circuit exceeding the synthesized, maximum acceptable charging waveform. The pre-charge circuit includes a sense resistor coupled to a power input side of the solid state switching device, with charging current through the pre-charge circuit being monitored via the sense resistor.
