  • Figure:1 Lamp Life Extender by ZVS (Zero Voltage Switching)

    Lamp Life Extender by ZVS (Zero Voltage Switching)

    Posted Sep 10, 2014 By Ravi Kumar
    The project is designed to develop a device to increase the life of incandescent lamps. Incandescent lamps exhibit very low resistance in cold condition due to which it draws high current while switched ON, resulting in fast failure. Random switching of lamps may switch the load at peak supply voltage. When such switching occurs while the lamp is having low resistance (cold condition) then the…
