ABSTRACT:
A current limited DC power controller is provided with an output stage having a controllable solid state switching device for conducting current between a pair of output terminals and a drive circuit for controlling the operation of this switching device in response to a control signal. A programmable current source is used to produce a reference current signal in response to a command signal and this reference current signal passes through a resistor to produce a reference voltage signal having a magnitude proportional to the command signal. When the power controller is off, the reference voltage signal is clamped to a preselected value. A second voltage signal proportional to the load current is combined with the referenced voltage signal and used to produce the control signal to which the drive circuit responds.
