  • Inrush current limiter
    Patent number: 5122724
    Abstract: A circuit for limiting the inrush current in DC to DC and DC to AC power supplies. The circuit utilizes a small capacitor for taking a charge which slowly turns on a FET transistor placed in series with a large filter capacitor; the slowly reducing resistance of the transistor provides the desired inrush current limiting.
