Abstract
PURPOSE: To make it possible to plural stable controls properly easily and surely, by switching the switching element to plural control states by the external signal to perform controls.
CONSTITUTION: Switching element 14 such as a thyristor connected in series to load 13 is switched to plural control states (in this case, different ignition phase angles) according to the external signal applied to terminals 16a and 16b, thereby controlling electric power supplied to the load. In this case, the output of voltage detecting circuit 15, which issues the output signal until a prescribed voltage value of AC power source 1 is detected, and the output obtained by causing the output of voltage detecting circuit 15 to pass through inverting circuit 17 and delay circuit 18 are applied to signal switching circuit 16 and are switched according to the external signal applied to terminals 16a and 16b of signal switching circuit 16 and are supplied to the gate of switching element 14, so that ignition phase angles of switching element 14 can be switched according to the external signal to control electric power supplied to the load.
