A kind of motor driven switch power supply of low-power consumption
Technical field
The present invention provides a kind of motor driven switch power supply of low-power consumption.
Background technology
At present under the promotion of Internet of Things (Internet of Things, IoT) technology megatrend, smart home
(smart home)This field is in the ascendant.But as the same table of smart home important application scene, motorized window and
The motor drive power supply of the industries such as garage door, on the one hand, very recently still based on the Industrial Frequency Transformer such as annular and square.Work
Frequency power transformer volume is heavy, and input range is narrow, and efficiency is low.On the other hand, although existing at present much use Switching Power Supply conduct
The case of the driving power supply of motor, but it is increasing with Based Intelligent Control demand, and electric drive power supply needs to be continuously added new
Circuit.Newly-increased circuit means that the increase of energy consumption, but under the environmental consciousness that people increasingly improve, various countries set to electrical equipment
The horsepower requirements of standby especially household electrical appliance are more and more harsh, and motor drive power supply is faced with increasingly harsher energy consumption (especially
It is the energy consumption under zero load) challenge.Accordingly, it would be desirable to a kind of can low cost, motor driven switch that is can meeting various countries' energy consumption standard
Power supply.
The content of the invention
A kind of motor driven switch power supply it is a primary object of the present invention to provide low-power consumption, its structure for passing through uniqueness
Design, not only realizes the increase (function that motor positive and inverse drives) of control function, and total no-load power consumption of power supply is also controlled
That makes is preferable, meets industry correlation energy consumption standard, and circuit realiration is simple, and cost is relatively low.
The technical solution adopted by the present invention is:A kind of motor driven switch power supply of low-power consumption, including rotating selection is opened
Pass, current rectifying and wave filtering circuit, low-power consumption exchange input detecting circuit, Switching Power Supply main circuit and rotating process circuit, wherein,
The current rectifying and wave filtering circuit, the Switching Power Supply main circuit, rotating process circuit, low-power consumption exchange input detecting circuit order successively
It is serially connected end to end, the rotating selecting switch is connected in the current rectifying and wave filtering circuit in parallel and input detection is exchanged with the low-power consumption
Between circuit.
Rotating selecting switch switch is a switch for single-pole double throw, can be integrated in power source internal, it is also possible to outward
It is placed in outside power supply, when one side is pushed, motor is rotated forward, on the contrary motor reversal.
The low-power consumption exchanges input detecting circuit, first carries out partial pressure to exchange input, rectification is then carried out, to electricity after rectification
Appearance is charged, and finally produces a current signal for pulsation whenever exchange input zero passage, and the Switching Power Supply main circuit will be whole
Flow the voltage signal needed for the high-voltage signal for filtering changes into motor;Rotating process circuit, the controller of the part is according to low
Power consumption exchanges the signal of input detecting circuit, produces corresponding drive signal to drive H-bridge circuit, realizes that output voltage is positive and negative anti-
To function.
Beneficial effects of the present invention are:The present invention includes rotating selecting switch, current rectifying and wave filtering circuit, low work(in structure
Consumption exchange input detecting circuit, Switching Power Supply main circuit and rotating process circuit, wherein, the current rectifying and wave filtering circuit, this opens
Order is serially connected end to end successively to close electric power main circuit, rotating process circuit, low-power consumption exchange input detecting circuit, and this is just
Reversion selecting switch is connected in parallel between the current rectifying and wave filtering circuit exchanges input detecting circuit with the low-power consumption.It passes through uniqueness
Structure design, not only realize the increase (motor positive and inverse drive function) of control function, and power supply total unloaded work(
It is preferable that consumption is also controlled, and meets industry correlation energy consumption standard, and circuit realiration is simple, and cost is relatively low.

Specific embodiment
As shown in Figure 1 to Figure 2 for one kind of the invention is preferably embodied example, a kind of motor of low-power consumption drives to be opened
Powered-down source, including rotating selecting switch 10, current rectifying and wave filtering circuit 20, low-power consumption exchange input detecting circuit 30, Switching Power Supply
Main circuit 40 and rotating process circuit 50, wherein, the current rectifying and wave filtering circuit 20, the Switching Power Supply main circuit 40, rotating
Order is serially connected process circuit 50, low-power consumption exchange input detecting circuit 30 end to end successively, the rotating selecting switch 10
It is connected in parallel between the current rectifying and wave filtering circuit 20 exchanges input detecting circuit 30 with the low-power consumption.
Further, rotating selecting switch switch is a switch for single-pole double throw, can be integrated in power source internal, also may be used
To be placed on outside power supply, when one side is pushed, motor is rotated forward, on the contrary motor reversal;
The current rectifying and wave filtering circuit, into direct current be input into exchange input rectifying by it.
The low-power consumption exchanges input detecting circuit, first carries out partial pressure to exchange input, rectification is then carried out, to electricity after rectification
Appearance is charged, and finally produces a current signal for pulsation whenever exchange input zero passage, and the Switching Power Supply main circuit will be whole
Flow the voltage signal needed for the high-voltage signal for filtering changes into motor;Rotating process circuit, the controller of the part is according to low
Power consumption exchanges the signal of input detecting circuit, produces corresponding drive signal to drive H-bridge circuit, realizes that output voltage is positive and negative anti-
To function.
Case study on implementation of the invention provides a kind of motor driven switch power supply of low-power consumption, not only realizes control function
Increase (motor positive and inverse drive function), and power supply total no-load power consumption also control it is preferable, meet industry correlation energy
Consumption standard, and circuit realiration is simple, and cost is relatively low.
