Abstract
The utility model relates to an 110V voltage-multiplying circuit in brush direct-current motor drive. A circuit input end is connected with a bridge rectifying circuit, the bridge rectifying circuit is connected with a socket, and the socket is connected with a circuit output end. The circuit is connected with the socket, two pins of a plug connector are connected or disconnected via a short circuit plug, and then the rectified voltage of the socket CN7 is always 300VDC. By aid of the 110V voltage-multiplying circuit, the same product can be used in different markets, thereby saving production cost. During usage of the 110V voltage-multiplying circuit, different voltages are switched by the socket CN7, thereby realizing switch between 110V and 220V conveniently.
Description
Technical field
The utility model relates to voltage handoff technique field in the industrial electrical network, specifically, is a kind of 110V voltage-multiplying circuit that has in the driving of brush direct current machine.
Background technology
Different countries and regions industrial electrical network voltage differences, the different standard of the 110V/220V of interchange is arranged, therefore when motor and driver are sold different voltage forms national, the motor and the driver that adapt to 110V or 220V need be provided respectively, this has increased the complexity of producing and selling, and causes cost to rise.
Existing this solution of selling 110V or 220V product respectively at different markets is not only at the bottom of cost height, the efficient, and time-consuming, waste resource.Different market demands sell the product of different model, have increased the kind of the material of producing and selling, maintenance, have increased significant cost.
If can invent the compatible different voltage of a kind of energy, can just can address the above problem at the product of 110V/220V network system switching, also will be a very big contribution to network system.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of 110V voltage-multiplying circuit that has in the driving of brush direct current machine is proposed, the voltage that energy is compatible different, at any time switch in the 110V/220V network system, solved because the voltage form difference is given the producing and selling of motor, driver, the difficult problem that maintenance brings.
The utility model is achieved through the following technical solutions:
110V voltage-multiplying circuit in the driving of brush direct current machine is arranged, and circuit input end connects a bridge rectifier, and described bridge rectifier connects a socket, described socket connecting circuit output.
Described socket is provided with at least two pins.
Described pin is provided with a short circuit plug that matches with it and use.
Operation principle of the present utility model is: when input voltage (AC IN) is the 110V alternating current, with a short circuit plug first pin on the CN7 (socket) and second pin are coupled together, voltage after the rectification (BUS+) just can reach about 300VDC, is equivalent to the voltage of 220VAC rectification; When input voltage is the 220V alternating current, pull up the plug of CN7, the voltage after the rectification (BUS+) just can reach about 300VDC.
Therefore, at different voltage (110V and 220V), by connecting CN7 or do not connect the pin of CN7, the voltage on the later CN7 of rectification as a result all is 300VDC all the time.So, though the input voltage difference, control circuit, motor all are the same, different market, can use same product; During use,, use socket CN7 to switch at different voltage.
Beneficial effect: the utility model has the 110V voltage-multiplying circuit in the driving of brush direct current machine, by in circuit, connecting a socket, by connecting or disconnection with two pins of short circuit plug with plug connector, the voltage that obtains on the later CN7 of rectification all is 300VDC all the time.Make different market, can use same product, saved production cost; During use,, use socket CN7 to switch, realize the switching of 110V/220V easily at different voltage.
Description of drawings
Fig. 1 has the schematic diagram of the 110V voltage-multiplying circuit in the driving of brush direct current machine for the utility model.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated: present embodiment is being to implement under the prerequisite with technical solutions of the utility model; provided detailed execution mode and concrete operating process, but protection range of the present utility model is not limited to following embodiment.
Embodiment:
Referring to Fig. 1, present embodiment comprises circuit input end 1, and circuit input end 1 connects a bridge rectifier, bridge rectifier connects a socket 3, socket 3 is provided with two pins, and plug-in pin 3 is provided with a short circuit plug 31 that matches with it and use, socket 3 connecting circuit outputs 2.
When current input terminal 1 voltage (AC IN) when being the 110V alternating current, with a short circuit plug 31 first pin on the socket 3 and second pin are coupled together, circuit output end 2 voltages (BUS+) after the rectification just can reach about 300VDC, are equivalent to the voltage of 220VAC rectification; When circuit input end 1 voltage is the 220V alternating current, pull up the plug of socket 3, circuit output end 2 voltages after the rectification just can reach about 300VDC.
Therefore, at different voltage (110V and 220V), by the pin of gang socket 3 or not gang socket 3, the voltage on the later socket 3 of rectification as a result all is 300VDC all the time.So, though the input voltage difference, control circuit, motor all are the same, different market, can use same product; During use,, use socket 3 to switch at different voltage.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
