Abstract

PURPOSE:To prevent a phase control element to stop due to resonance current, by providing communication signals when the sudden change of voltage at the both ends off the phase control element is detected on an apparatus for providing the output of the phase control element for a load via a filter circuit. CONSTITUTION:On an apparatus for controlling AC power provided through AC power source with a phase control element 6 like TRIAC and for providing power for a load 5 via a filter circuit consisting of a choke 3 and a condenser 4, a detector for detecting the sudden change of the voltage at the both ends of the element 6 is provided in the gate circuit of the element 6. The detector is formed by connecting the series unit, for example, of a condenser 7 and a resistance 8 to a gate. At the time of, detecting the sudden change of the voltage at the both ends, gate current is arranged to be provided for the phase control element 6. In this manner, the resonance current of the filter circuit is generated on starting the communication signals of the element 6, and even if the element 6 stops, it can start again immediately.
