When the driving controlling circuit is just powered on, a master control silicon controlled rectifier is in a conducting state, now a driving circuit is operated in a full-bridge ratification mode, meanwhile an RC circuit of a control circuit is operated in a charging mode, a threshold driving circuit is started after the RC circuit maintained in the charging mode reaches a threshold voltage, the threshold driving circuit drives the master control silicon controlled rectifier to be turned off, now the driving circuit is operated in a half-wave rectification mode, and an output voltage drops. The fact that a 220V alternating current is changed to a 180V direct current and then is changed to a 90V direct current is achieved, a starting interval of the next time can be controlled by the RC circuit, strong excitation starting of a brake is achieved, low currents are maintained, overheating does not occur, and starting can be carried out with high frequency.
Description
Technical field
The utility model relates to a kind of break Drive and Control Circuit.
Background technique
Break starts needs DC excitation, and the power frequency electricity is to exchange, change alternating direct-current so need the break control panel, come because break needs a stronger magnetic field that break armature is inhaled when starting, but keep this suction and state not to need so strong magnetic field, and the corresponding high electric current in strong magnetic field, heating can be very big, so when keeping suction and state, voltage is dropped to half, 1/4th before heating just drops to like this.
Summary of the invention
The utility model purpose is to provide a kind of break Drive and Control Circuit, and it realizes the strong excitatory startup of break, and low current is kept, and is not overheated, and can high-frequencyly start.
In order to solve these problems of the prior art, the technological scheme that the utility model provides is:
A kind of break Drive and Control Circuit, comprise drive circuit and control circuit two-part, civil power carries out voltage transitions rear driving break through drive circuit, control circuit is used for the work of control drive circuit, drive circuit comprises full bridge rectifier, half-wave rectifying circuit and master control controllable silicon, the controlled circuit control of described master control controllable silicon for switching full-bridge rectification and two kinds of mode of operations of one way rectifier.
For technique scheme, the inventor also has further optimization embodiment.
As optimization, control circuit comprises RC circuit and thresholding drive circuit, and described RC circuit is after being full of electricity and namely reaching threshold voltage, and the thresholding drive circuit then cuts out the master control controllable silicon, finishes the switching between full bridge rectifier, half-wave rectifying circuit.
Further, also be provided with automatic discharge circuit in the described control circuit, described automatic discharge circuit links to each other with the RC circuit, is used for the automatic discharge that the RC circuit is full of behind the electricity RC circuit is made zero.
As optimization, drive circuit comprises full bridge rectifier, half-wave rectifying circuit and master control controllable silicon that diode constitutes that four diodes are formed, the positive pole of the diode in the half-wave rectifying circuit links to each other with master control silicon controlled negative electrode, negative pole is with after master control silicon controlled anode links to each other, and connecting with full bridge rectifier constitutes drive circuit again.
Than solution of the prior art, the utility model advantage is:
1.The utility model has been described a kind of break Drive and Control Circuit, when Drive and Control Circuit just powers on, the master control controllable silicon is on state, this moment, drive circuit works was in the full-bridge rectification pattern, the RC circuit working of control circuit is in charge mode simultaneously, and the thresholding drive circuit starts after the RC circuit that keeps charged state reaches threshold voltage, and the thresholding drive circuit drives the master control controllable silicon and cuts out, drive circuit works is in the one way rectifier pattern at this moment, and output voltage descends.Realize that alternating current 220V is converted to direct current 180V and is converted to direct current 90V then, and start at interval next time and can controlled by the RC circuit that realize the strong excitatory startup of break, low current is kept, and is not overheated, and can high-frequencyly start.
2.After the magnitude of voltage of RC circuit reached threshold voltage, automatic discharge circuit action was made zero the RC circuit by automatic discharge, prepared for start next time, avoided repeated priming to cause the RC unstable phenomenon of working.
