Capacitor Energy Storage Circuit Breaker
While mechanical circuit breakers are robust to temporary over-voltage and over-current stresses, a solid-state circuit breaker (SSCB) is less capable of absorbing this energy. To circumvent this, our approach is to divert the current to an energy storage component, namely, a capacitor, using a fast semiconductor switch.

Can a Bad Capacitor Trip a Breaker?
When a capacitor has been damaged or gone bad, it can no longer store the same amount of energy it used to and so the power that goes through the circuit becomes too much and trips the breaker. To prevent this from happening, it''s important to inspect capacitors regularly and replace them when they show signs of damage or age.
