Abstract
The utility model relates to a bidirectional silicon controlled alternating-current switch consisting of an LED (light-emitting diode) and a photosensitive resistor. A bidirectional silicon controlled alternating-current switch circuit coupled by the phi 3 red-light LED and the photosensitive resistor is adopted, so that the switch only comprises three components, thus being efficient and succinct. By adopting general components, the bidirectional silicon controlled alternating-current switch is low in design cost, simple in structure, small in volume, and simple and fast in control and driving, and can be widely used in equipment and self-energy home power automatic management systems.
Description
Affiliated technical field
The utility model relates to a kind of bidirectional triode thyristor alternating-current switch of being made up of LED and photo resistance, the electronic switch and the power supply automated management system of suitable device power supply (DPS).
Background technology
At present, be used for the interchange control switch of device power supply (DPS), mainly use relay switch, controllable silicon solid-state switch and ghyristor circuit switching circuit, be characterized in that cost is higher, circuit is loaded down with trivial details.Modern energy conservation needs the more control switch that exchanges, and needs a kind of low cost, efficient simple and direct interchange control switch.
Summary of the invention
At above-mentioned condition, the utility model provides the bidirectional triode thyristor of being made up of LED and photo resistance alternating-current switch, the electronic switch and the power supply automated management system of suitable device power supply (DPS).
The technical scheme that its technical problem that solves the utility model adopts is: adopt the bidirectional triode thyristor alternating current switching circuit that is of coupled connections by φ 3 red-light LEDs and photo resistance, only 3 elements are efficiently simple and direct.
The beneficial effects of the utility model are, adopt the universal component design cost low, simple in structure, and volume is little, and controlling and driving is simple and direct, can be widely used in equipment and intelligent home power supply automated management system.
Description of drawings
Below in conjunction with accompanying drawing and example the utility model is further specified.
Among the figure. be the utility model circuit theory diagrams.
Specific embodiments
Among the figure. adopt the bidirectional triode thyristor alternating current switching circuit that is of coupled connections by φ 3 red-light LEDs and photo resistance, 3 elements only, optocoupler assembly: be by LED and the direct coupling of photo resistance, and with outer light Isolated Shield, the photo resistance two ends directly are connected with bidirectional triode thyristor G end, A2 end, have both simplified the silicon controlled drive circuit, simultaneously because photo resistance is to drive silicon controlled by change in resistance, the characteristic that soft start is arranged helps device power supply (DPS) safety and self alternating current switching circuit safety.
.V+ is a controlling and driving voltage among the figure, 2 volts of voltages of demand only, 1 milliampere of Control current.
Bidirectional triode thyristor alternating-current switch cost is low, and is simple in structure, and volume is little, is applied in many Application Design.
