Patent ID: 8416550

Claim:
A solid state circuit breaker for disrupting direct current should the direct current have a voltage that surpasses a predetermined threshold voltage, said circuit breaker comprising: a power transistor in series with said direct current, wherein said power transistor has an on state and an off state, and wherein said power transistor disrupts said direct current only when in said off state; a first optoisolator that contains a first LED and a first transistor, wherein said first LED has a minimum operating voltage; a threshold resistor through which said direct current passes, wherein said threshold resistor creates a voltage differential, and wherein said voltage differential is supplied to said first LED and causes said first LED to activate said first transistor only if said voltage differential is greater than said minimum operating voltage; wherein said first transistor causes said power transistor to change from said on state to said off state when activated; and a regenerative circuit having a reset switch, wherein said regenerative circuit maintains said first transistor in an activated state, once activated, even if said voltage differential drops below said minimum operating voltage.
