  • Gradually reducing resistive clamp
    Patent number: 8553381
    Abstract: A voltage spike protection system minimizes a voltage spike by connecting a resistive clamp to a power source when the voltage spike is detected. The voltage spike detection system disconnects the resistive clamp after a portion of the voltage spike is dissipated.
    Type: Grant
