Abstract
A current sensing system includes a pre-calibrated busbar, a voltage sensor, a temperature sensor and a controller. The pre-calibrated busbar has a known resistance, a known variation in resistance with respect to temperature and known dimensions. The voltage sensor detects a difference in voltage between a first location and a second location on the pre-calibrated busbar. The temperature sensor detects an ambient temperature of the pre-calibrated busbar. The controller determines a resistance of the busbar between the first location and the second location based on the known resistance, known variation in resistance, known dimensions and the ambient temperature. The controller additionally determines a current flowing through the pre-calibrated busbar based on the difference in voltage and the determined resistance. The current sensing system has numerous applications including using the determined current to control an operating condition of a solid state circuit breaker or a solid state power controller.
