力制御回路。[Claims for Utility Model Registration] (1) An AC load that controls the power supplied to an AC load such as a lamp or an inductive load so that inrush current at startup is suppressed by the presence of a non-conducting period of an AC switch element. In the power control circuit, the AC switch element has different trigger sensitivities depending on two trigger modes corresponding to positive and negative half cycle periods of AC, and the trigger voltage is supplied to the AC switch element. 1. A power control circuit for an AC load, characterized in that the part is configured to generate a low trigger voltage that becomes conductive only in the half cycle with higher trigger sensitivity at startup. (2) The power control circuit for an AC load according to claim 1, wherein the AC switch element is comprised of an anti-parallel circuit of two types of thyristors having different trigger sensitivities. (3) Utility model registration claim No. (1) characterized in that the trigger voltage supply section is composed of an integrating circuit.
The power control circuit for an AC load according to any one of paragraphs 1 and 2.
