Abstract
Some embodiments of the inventive subject matter provide an apparatus for driving a shunt trip actuator for a circuit breaker or other switch. The apparatus includes an energy storage device and an accumulator circuit configured to store energy in the energy storage device responsive to a shunt trip control signal. The apparatus further includes a detector circuit configured to generate a detection signal responsive to a state of the energy storage device meeting a predetermined criterion and a driver circuit configured to drive the shunt trip actuator using the energy stored in the energy storage device responsive to the detection signal.
