Abstract
PURPOSE: To realize the supply of the adjustment output for the plural steps with operation of the single switch in several times by giving the phase control to the thyristor via the sag-tension oscillation circuit and the plural-step phase setting circuit including the memory elements.
CONSTITUTION: Triac 4 is connected in series to load 5, and 1st-and 2nd-step phase setting circuits 20 and 40 are installed to the circuit which supplies the ignition pulse of triac 4 from sag-tension oscillation circuit 60. With power switch 3 turned on, the charge voltage of circuit 60 is charged with the voltage caused by Zener diode 14 since neither circuit 20 nor 40 functions. When switch 3 is turned on and off, circuit 20 functions, and thus the charge voltage of circuit 60 features the value which is voltage-divided via resistances 35 and 34. Furthermore with switch 3 turned on and off, curcuit 40 functions, and thus the charge voltage of circuit 60 features the value divided via resistances 35, 34 and 48. As a result, the conduction angle of triac 4 varies.
