Abstract
A direct current (DC) solid state circuit breaker includes a first terminal, a second terminal, a power electronics section comprising at least a first transistor switch, and one or more airgap sections that include at least a second transistor switch and a third transistor switch. The second transistor switch and the third transistor switch arranged in back to back configuration such that i) the second transistor switch is configured to interrupt current flowing in a first direction from the first terminal to the second terminal and ii) the third transistor is configured to interrupt current flowing in a second direction from the second terminal to the first side terminal. The DC solid state circuit breaker also includes a controller configured to detect a fault condition and control operation of the power electronics section and the one or more airgap sections in response to detecting the fault condition.
