Description
Technical field
The present invention relates to switching technique field, specifically a kind of single live wire switch supply module.
Background technology
In order to make household light, the switch control rule of electrical equipment becomes intelligent, and single live wire intelligent switch progressively replaces traditional mechanical switch on wall.Because electronic intelligence lighting switch itself all needs to consume certain electric current, and average family is mostly the wiring of single live wire both at home and abroad, institute to produces single fiery power taking technology, and plain conductor is more and more expensive in addition, and the cost walking single line implements the cost of single live wire increase more far above switch itself.Because the standby power taking of single live wire switch is that the electric current by flowing through load is powered to the control circuit of switch, if the little stand-by circuit that will cause of standby input current can not work, if standby input current will cause greatly load current unstable.
Summary of the invention
Not enough for above-mentioned prior art, the invention provides a kind of standby current low, the single live wire switch supply module little to load effect.
One provided by the invention single live wire switch supply module is achieved through the following technical solutions:
A kind of single live wire switch supply module, it is characterized in that: comprise rectifier bridge, diode, first electric capacity, second electric capacity, one-way SCR, bidirectional triode thyristor, first resistance, second resistance, described rectifier bridge successively with the second resistance and load in series after incoming transport electricity, two other terminals one end ground connection of rectifier bridge, the other end connects the positive pole of diode and the positive pole of one-way SCR, the negative pole of described diode connects the input of electronic switch and one end of the second electric capacity respectively, the other end ground connection of the second electric capacity, the output of electronic switch connects the first resistance, the other end of the first resistance connects control pole and first electric capacity of one-way SCR, the other end ground connection of the first electric capacity, the minus earth of described one-way SCR, one pole of described bidirectional triode thyristor connects live wire, control pole and another pole of bidirectional triode thyristor are connected the two ends of the second resistance respectively.
The invention has the beneficial effects as follows:
1, adopt controllable silicon as driving element, silicon controlled trigger current is little, pressure drop is little, and whole circuit power consumption is low, little to load effect, has ensured the stable operation of load.
2, ensure that the stable of output voltage, solve the problem affecting circuit power itself because of the change of load current, carrying load ability is strong.
Accompanying drawing explanation
Fig. 1 is circuit diagram of the present invention.
Embodiment
For making the object of the application, technical scheme and advantage clearly, below in conjunction with drawings and the specific embodiments, the application is described in further detail.
One list live wire switch supply module as shown in Figure 1, comprise rectifier bridge Q, diode D, first electric capacity C1, second electric capacity C2, unidirectional controllable silicon S CR1, bidirectional triode thyristor SCR2, first resistance R1, second resistance R2, incoming transport electricity after described rectifier bridge Q connects with the second resistance R2 and load L successively, two other terminals one end ground connection of rectifier bridge Q, the other end connects the positive pole of diode D and the positive pole of unidirectional controllable silicon S CR1, the negative pole of described diode D connects the input A of electronic switch and one end of the second electric capacity C2 respectively, the other end ground connection of the second electric capacity C2, the output of electronic switch connects the first resistance R1, the other end of the first resistance R1 connects control pole and the first electric capacity C1 of controllable silicon SCR 1, the other end ground connection of the first electric capacity C1, the minus earth of described unidirectional controllable silicon S CR1, one pole of described bidirectional triode thyristor SCR2 connects live wire, control pole and another pole of bidirectional triode thyristor SCR2 are connected the two ends of the second resistance respectively, described switch negative pole C ground connection.
When electronic switch cuts out, unidirectional controllable silicon S CR1 and bidirectional triode thyristor SCR2 ends, and load L is not energized, when electronic switch is opened, electronic switch B holds and triggers unidirectional controllable silicon S CR1 conducting, and unidirectional controllable silicon S CR1 conducting and then bidirectional triode thyristor SCR2 conducting of setting out, load L obtains electric.
The above embodiment only represents embodiments of the present invention, and it describes comparatively concrete and detailed, but can not be interpreted as limitation of the scope of the invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to scope.
