Abstract
A power interruption circuit for use in a power distribution module is provided. The power interruption circuit is configured to provide power to a load and includes a shunt resistor, a plurality of switches, and microprocessor. The microprocessor is configured to determine a digitized value of a current flowing through the shunt resistor, determine a digitized value of an output voltage of the power interruption circuit, calculate, from the digitized current value and the digitized output voltage value, a power provided by the power interruption circuit to the load, compare the calculated power to a threshold power level, and control the plurality of switches based on the comparison.
