することを特徴とした電力制御回路。[Claims for Utility Model Registration] It has a zero-cross detection unit that detects the zero-cross point of an AC signal supplied from an AC power supply, and the AC signal is turned on by a power switch control unit in accordance with the detection output from the zero-cross detection unit.・In a power control circuit that controls the amount of power supplied to a load by turning off and controlling the sending of multiple trigger pulses, a random number is generated to randomly control on/off of the power switch control section. A random number generating section, and a power consumption designation input section for presetting a desired power consumption amount in the power switch control section, and a certain period of time corresponding to the power consumption amount set from the power consumption designation input section. The power switch control section sends out the number of trigger pulses per hit, turns the trigger pulses into one or more continuous pulses by the random number generating section, and randomizes the combination and sending interval, and sends them out from the power switch control section. power control circuit.
