  • Normally closed solid state relay using normally open components
    Patent number: 11777490
    Abstract: A solid-state relay includes a semiconductor switch and a voltage boost block. The semiconductor switch has a control input, which causes the semiconductor switch to shift from an open, non-conducting position to a closed, conducting position when a voltage is applied to the control input. The voltage boost block includes a boost converter and a ground connector. A voltage output of the semiconductor switch is electrically connected to a voltage input of the boost converter. A voltage output of the boost converter is electrically connected to the control input. The ground connector of the boost converter is electrically connected to a voltage input of the semiconductor switch When the semiconductor switch is in the closed position, the semiconductor switch is maintained in a closed position in the absence of another control signal.
