Problems solved by technology

[0002] At present, the power-taking method of smart switches on the market needs to be powered by a single live wire, and a single-fire power-taking scheme is adopted. When the lights are turned off, a certain amount of current needs to be stolen. Now, energy-saving lamps - energy-saving lamps, LED lights, etc. are commonly used. Due to the inherent way of taking power, if the stolen current is too large, it will cause the lamp to produce ghost fire (flicker)

Embodiment Construction

[0015] Embodiments of the present invention are described in further detail below in conjunction with the accompanying drawings:

[0016] A single live wire power-taking circuit based on micro-switch or optocoupler control, the main advantage is that micro-switch or optocoupler can be used to control high-voltage circuits, such as figure 1 As shown, it includes a high voltage divider unit 1, a micro switch optocoupler unit 2, an NMOS control unit 3 and a PMOS control unit 4; The optocoupler unit connects the divided voltage to the NMOS control unit and controls the conduction of the NMOS control unit; the output terminal of the NMOS control unit is connected with the PMOS control unit for further guiding the connection of the PMOS control unit.

[0017] In this embodiment, the high-voltage divider unit 1 divides 220VAC into a voltage of about 10VAC, and the microswitch optocoupler unit 2 is used to connect the divided voltage to the NMOS control unit 3, which can control the c...

Abstract

The invention relates to a single-live-wire power taking circuit based on micro switch or optical coupler control, which is characterized in that the circuit includes a high voltage dividing unit, a micro switch and optical coupler unit, an NMOS control unit and a PMOS control unit; the high voltage dividing unit is used to divide the voltage of a mains supply, and the output end connects the divided voltage to the NMOS control unit through the micro switch and optical coupler unit and controls the conduction of the NMOS control unit; and the output end of the NMOS control unit is connected with the PMOS control unit to further guide the connection of the PMOS control unit. The flickering phenomenon of lamps is avoided.

Description

technical field [0001] The invention belongs to the field of electronic technology, in particular to a single live wire power-taking circuit controlled by a micro switch or an optocoupler. Background technique [0002] At present, the power-taking method of smart switches on the market needs to be powered by a single live wire, and a single-fire power-taking scheme is adopted. When the lights are turned off, a certain amount of current needs to be stolen. Now, energy-saving lamps - energy-saving lamps, LED lights, etc. are commonly used. Due to the inherent way of taking power, if the stolen current is too large, it will cause will-o'-the-wisps (flickering) of the lamps. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, and provide a single live wire power-taking circuit based on micro-switch or optocoupler control, which can effectively control the formation of the power-taking circuit, thereby elimin...
