Abstract

The invention discloses an adjustment device. The adjustment device comprises a power supply circuit, a main control circuit, and a switch circuit, wherein the power supply circuit includes a zero point detection module for detecting a zero point of the accessed AC to generate a zero point signal; the main control circuit is used to receive the zero point signal and an adjustment signal, the adjustment signal is detected to acquire an adjustment mode and the state value of a load, a control signal transmission mode is thus determined based on the zero point signal, the adjustment mode and thestate value, the control signal is transmitted according to a transmission mode, the load is powered by the AC, and the adjustment mode is used to indicate which part of the AC cycle is to transmit the control signal; the switch circuit includes a switch element, the switch circuit is conducted when the control signal from the main control circuit is received and cut off when the control signal isnot received, and the working state of the load is adjusted. Thus, the adjustment device can reasonably select front phase cutting or rear phase cutting according to load of different properties to perform adjustment in relative to the load.

Description

technical field [0001] The present application relates to the technical field of adjusting the working state of a load, in particular to an adjusting device. Background technique [0002] There are two main types of AC phase-cut power regulators (dimming or speed regulation) that appear on the market at present: one is the cutting-edge phase-cut power regulator based on silicon controlled rectifiers; the other is based on dual MOS tubes [metal (metal )-oxide (oxide)-semiconductor (semiconductor) field effect transistor] trailing edge phase-cut dimmer. However, these two power regulators are suitable for loads of different natures, and most of them are dedicated to dimming or speed regulation. For example, the leading-edge phase-cutting mode is suitable for regulating inductive and resistive loads, and the trailing-edge phase-cutting mode is suitable for regulating capacitive loads. In the case of loads of different natures, a power regulator with a single phase-cutting mod...
