Abstract
PURPOSE: To obtain the AC constant voltage unit of small size without requiring pulse transistors, by connecting the series circuit of full wave rectifying circuit and gate resistor in parallel with the series circuit consisting of load and Triac controlling the load.
CONSTITUTION: The load L is controlled with the Triac 12 which is controlled with the gate resistor 14 in series connection with the full wave rectifying circuit 13. To the full wave rectifying circuit 13, the phase control circuit consisting of the series circuit of resistor 15 and SCR16, resistors 21W25, capacitor 26, Zener diode 27 and PUT28 is connected. If AC power input 11 is variated, the gate voltage of PUT28 is fluctuated according to it, and the phase of PUT28 turned on is variated. As a result, the trigger phase of SCR16 and Triac 12 is changed and a given value of voltage is fed to the load L.
