Abstract
Solid state power controllers in various configurations are provided. One such solid state power controller includes a power connector, a load connector and at least one communication connector, a solid state switch electrically connectable between the power connector and the load connector, where the switch includes an input, a microcontroller coupled to the input of the solid state switch, and current sensing circuitry coupled to the microcontroller and configured to sense a current flowing through the solid state switch, the current sensing circuitry including an amplifier having an offset error, where the current sensing circuitry is configured to generate a signal indicative of the current flowing through the solid state switch, and bias the generated signal to a predetermined level to substantially eliminate the offset error in the amplifier.
