相制御装置。[Claims for Utility Model Registration] An AC power source; means for detecting a zero-crossing point where the output voltage of the AC power source becomes zero; means for generating a clock signal having a frequency higher than the frequency of the AC power source; By counting the clock signal in response to the output from the detection means, the derivation of a trigger signal for phase-controlling the load at a predetermined phase angle is started, and the output from the next zero-cross detection means is started. Trigger signal generation means that completes the derivation of the trigger signal in response to the input signal; means that performs phase control so that power is supplied from the AC power source to the load during the period when the input signal is applied; and the zero-cross detection means. a retriggerable monostable circuit that, in response to the output of the monostable circuit, derives a signal that lasts for a predetermined period of time equal to or more than half a cycle of the AC power source; and in response to a signal from the monostable circuit, the trigger signal A phase control device for a load, comprising means for applying the input signal to a control means.
