Stabilized voltage is in charge of to when receiving a standard like common diode character.

 

 

When stabilized voltage canal is receiving a standard reversely, when retrorse voltage is less than puncture voltage, retrorse electric current is very small, the dynamic resistance that present is very great. Working electric current is normally bigger, dynamic resistance is less, stabilized voltage performance is better.

 

When retrorse voltage is more than puncture voltage, the electric current that has shed diode increases quickly, but its tension of two end is basic however and constant, use this to be able to use stabilized voltage.

 

The application that stabilized voltage provides:

 

1, surge protects circuit

 

 

Stabilized voltage canal issues puncture in accurate voltage, this makes it can serve as limitation or protective component is used, because the stabilized voltage diode of all sorts of voltage can get, reason is particularly appropriate to this kind of application. The D of stabilized voltage diode in the graph is to had served as control protective parts of an apparatus. The D of stabilized voltage value that wants VS of power source voltage to exceed diode only guides, make J sucks relay add up to laden RL to part with power source.

 

2, in the television press protective circuit too

 

 

EC is a television advocate power supply pressing, when EC voltage is exorbitant, d guides, dynatron BG guides, its collector potential will by original tall n (5V) turns into low n, through biding one’s time the control of control line makes the television is entered bide one’s time protective condition.

 

3, electric arc restrains circuit

 

 

On inductance coil paralell connection receives an appropriate stabilized voltage diode (like also can accepting principle of a common diode) if, cut off in on-state when coil when, because its electromagnetism can release the high pressure of a generation to be absorbed by diode place, disconnect when switch so when, the electric arc of switch also was eliminated. This application circuit is used morer on industry, some more consistent relatively the electromagnetism of high-power sucks control circuit to use it.

 

4, circuit of series connection stabilized voltage

 

 

Circuit is here medium, series connection stabilized voltage is in charge of, the base of BG is in surely by clamp of D of stabilized voltage diode 13V, so its blast off extremely output constant 12V tension. This circuit has application below a lot of circumstances.

 

5, stabilized voltage is in charge of besides circuit of the stabilized voltage that make, still can regard one-time protection as circuit.

 

Be in for instance significant position, prohibit voltage is elevatory attaint is precious parts of an apparatus, the power source that can use canal of a stabilized voltage and the place is retrorse and shunt-wound, lift suddenly because of breakdown when power source voltage, after the stabilized voltage that exceeds stabilized voltage canal is worth, stabilized voltage canal turns quickly into retrorse puncture by off-state, direct power source short circuit, burn frit silk or resistor of current limliting protection, all load that protected spur track of this power source because exceed,won’t be pressed and damage.

 

 

Because this is planted,the stabilized voltage pipe that protection uses is not effective at ordinary times, repair in lash-up so in OK and temporary need not, seasoned maintenance technician is OK still even below emergency use local materials, tear open debus to regard maintenance as in short supply fittings use neatly.
