PURPOSE:To make it possible to freely set any given cycle and time of supplying a DC motive element with power, by controlling the trigger signal of an AC control element by the output of an oscillator. CONSTITUTION:An oscillation wave of a given cycle is outputted from the oscillator 7 and put into a control gate 8 together with a terminal C of a switch 6. A transistor 10 is turned ON by the output of the control gate 8. And then, a gate trigger current passes through VDD of DC stabilizing power source 2, a terminal T1 of an AC control element 13, a gate G and the transistor 10, and the AC control element 13 is conducted. While the AC control element 13 is conducted, a DC motive element 14 is supplied with negative half wave power of sine wave. Similary, when the terminals B and C of the switch 6 are connected, the DC motive element 14 is supplied with positive half wave power of sine wave. |
