  • Electronic circuit for controlling the supply voltage of electromagnets, electric motors, resistors, in single- and three-phase systems
    Patent number: 4449054
    Abstract: The control circuit comprises a solid state controlled switch coupled to a terminal of the mains and a terminal of the load the supply voltage whereof has to be controlled, and a non controlled solid state switch operatively coupled to the solid state controlled switch for setting, in cooperation with resistive and capacitive elements, also supplied by the mains, the conduction time of the controlled switch in such a way as to adjust at predetermined maximum and minimum levels the load supply voltage.
