Abstract: An electronic circuit breaker has a switching transistor for controlling current flow in a circuit. The switching transistor is controlled by a pair of complementary field-effect transistors to achieve very fast switching action. The electronic breaker is capable of sensing an overcurrent condition and interrupting current flow in less than a microsecond. The electronic circuit breaker also has an inductor for limiting the rate at which current can increase during the time delay between sensing an overcurrent and interrupting current flow.
