Abstract

PURPOSE:To enable to constitute a complicated control into a logic easily by a method wherein a trigger signal is sent to the gate of a direct AC controlling element from the controlling circuit in synchronization with a positive or a negative phase of an AC current circuit. CONSTITUTION:When the terminals A and C of a switch 9 are in ON position, a signal is supplied to the base of a transistor 12, an ON position is given to the transistor, passing through the common line of the AC circuit from the VDD of a DC stabilized power source 2 and then a trigger current flows to the line of VSS through the terminal T1 of the AC controlling element 14, a gate G, the transistor 12 and the like and the terminals T1 and T4 of the AC controlling element 14 are conducted. While the base voltage of the transistor 12 is maintaining VDD, the transistor 12 is in the OFF state and the AC controlling element 14 is in a nonconductive status, because the trigger current does not flow. Accordingly, while the AC controlling element 14 is in a continuity status, power is supplied using the half-wave formed sine wave in the form of DC pulse only when the AC controlling element 14 is in a continuity status for the element 15 which is operated by a direct current.
