The commutation circuit comprises a DC machine, a controller and a bridge circuit consisting of four triodes, wherein both input ends of the bridge circuit are respectively connected with two output ports of the controller, while both output ends are respectively connected with both ends of an electric machine; and the four triodes take base electrodes as input ends, and respectively take connected emitter electrodes and collector electrodes as output ends. The commutation circuit has simple circuit structure, low cost and convenient and flexible use.
Description
Technical field
The utility model relates to the commutation circuit technology, relates in particular to a kind of commutation technology of direct current machine.
Background technology
To the commutation of direct current machine, generally be to adopt mechanical commutation device in the prior art, perhaps adopt special-purpose commutation chip, the former needed powered-down before commutation, and very inconvenience operates; And the latter's cost is too high.
The utility model content
Technical problem to be solved in the utility model is: a kind of commutation circuit of direct current machine is provided, and this circuit structure is simple, and is easy to use flexible, and cost is low.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of commutation circuit of direct current machine, include direct current machine and controller, this circuit also includes the bridge circuit of being made up of four triodes, two inputs of this bridge circuit are connected to two output ports of controller, the two ends that two outputs are connected to motor, described four triodes all are input with the base stage, and connect as output with emitter and collector respectively.
The beneficial effects of the utility model are:
Embodiment of the present utility model is by constituting bridge circuit with four triodes, utilize controller to open and close corresponding two triodes, thereby the positive and negative stream of Switching power is realized the rotating of direct current machine, reaches anti-phase effect, circuit structure is simple, cost is low and easy to use flexibly.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Description of drawings
Fig. 1 is the circuit theory diagrams of an embodiment of commutation circuit of the utility model direct current machine.
Embodiment
With reference to figure 1, this figure is the circuit theory diagrams of an embodiment of commutation circuit of the direct current machine that provides of the utility model; As shown in the figure, the commutation circuit that present embodiment provides mainly is made up of single-chip microcomputer U1, triode Q1, Q2, Q3 and Q4, direct current machine M, and single-chip microcomputer U1 and direct current machine M are respectively by stabilized voltage power supply V
CC, V
DDPower supply, triode Q1, Q2, Q3 and Q4 are connected in the bridge circuit mode, two inputs of this bridge circuit are connected respectively to two output ports of single-chip microcomputer U1, wherein, two of single-chip microcomputer U1 output ports link to each other with the base stage of triode Q1, Q2, Q3 and Q4 respectively and be respectively arranged with resistance R 1, R2 on two incoming lines; Two outputs of bridge circuit are connected respectively to positive terminal and the negative pole end of direct current machine M, wherein, the emitter of the collector electrode of the positive terminal of direct current machine M and triode Q4 and Q1 links to each other, the negative pole end of direct current machine M links to each other with the collector electrode of triode Q2 and the emitter of Q3; In addition, between the emitter of Q1 and Q3 and collector electrode, also be parallel with sustained diode 1, D2 respectively.
When direct current machine M need just change, the controller U1 output port output high level that links to each other with resistance R 2 can make triode Q3, Q4 conducting; The controller U1 output port output high level that links to each other with resistance R 1 simultaneously can make triode Q1, Q2 end, thereby realizes that direct current machine M just changes.Otherwise, then realize direct current machine M counter-rotating.
Embodiment of the present utility model opens and closes corresponding two triodes by utilizing controller, thereby the positive and negative stream of Switching power is realized the rotating of direct current machine, reaches anti-phase effect.The present embodiment circuit structure is simple, cost is low and easy to use flexibly.
The above is a preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvement and deduction, these improvement and deduction also are considered as protection range of the present utility model.
