Abstract:
1. A solid state power controller possessing a power connector, a load connector and at least one communication connector, the solid state power controller comprising: a solid state switch coupled between the power connector and the load connector, the solid state switch comprising an input and configured to control a current flowing between the power connector and the load connector; a voltage measuring circuitry configured to measure a voltage at the power connector, the voltage measuring circuitry configured to minimize a current drawn from the power connector by the voltage measuring circuitry; and a microcontroller coupled to the input of the solid state switch and an output of the voltage measuring circuitry, the microcontroller configured to monitor a voltage at the power connector and to detect an overcurrent condition in the current flowing between the power connector and the load connector, wherein the voltage measuring circuitry comprises two diodes in a back to back configuration.
