Abstract

In order to drive it with compatible electromagnetic interference, a circuit breaker is charged with a high charging current until the drain current exceeds a current threshold. The circuit breaker is then charged further with a smaller charging current associated with the desired rate of rise, until the drain voltage falls below a predefined voltage threshold. The circuit breaker is then charged further with the high charging current for a predefined period. In order to close the circuit breaker, a nearly reverse sequence is followed.
