Valve of two-way brilliant brake is made by material of N-P-N-P-N5 layer semiconductor, external derivative also 3 electrode, its structure is shown like plan institute. Two-way brilliant brake provides the retrorse parallel connection that is equivalent to canal of brake of two one-way brilliant, but have a control pole only.

 

Canal of two-way brilliant brake and valve of one-way brilliant brake are same, also have spark control is characteristic. Nevertheless, its spark control character and canal of one-way brilliant brake have very big different, no matter why is indirect person planted in positive pole and cathode,this is of polarity voltage, should control in it only extremely on add on one to spark pulse, also no matter this pulse is of what polarity, so that canal of two-way brilliant brake guides,can connect.

 

The working voltage that because canal of two-way brilliant brake is in,in relief, cathode holds the post of He Ji sex secondhand can come true spark control, the main electrode that is in charge of because of this two-way brilliant brake also does not have the cent of zincous, cathode, call these two main electrode normally T1 electrode and T2 electrode, will receive the main electrode on P semiconductor material to call T1 electrode, will receive the electrode on N semiconductor material to call T2 electrode. 　

 

Two main electrode that are in charge of as a result of two-way brilliant brake do not have the cent that losing, voltage and the cent that are the same as peak value voltage instead also are worth without Zheng Xiangfeng in its parameter so, and use tension of a the greatest peak value only, the other parameter that two-way brilliant brake is in charge of is in charge of with one-way brilliant brake identical.

 

The volt-ampere character curve that two-way brilliant brake is in charge of has symmetry, if plan institute is shown.

The volt-ampere character curve that two-way brilliant brake is in charge of

 

 

Because two-way brilliant brake is in charge of, anti-espionage sex has symmetry, so it can be connected in any square guide, it is a kind of ideal communication switch parts of an apparatus.

 

 

(The judgement of 1) electrode and spark characteristic test

 

Block avometer buy Rx1, measure two-way brilliant brake to provide the block value of the department of aleatoric bipod, if measure the resistor between some foot and other bipod to all be infinity, criterion this foot is T2 pole.

 

After deciding T2 pole, can assume foot of the some in the others bipod is T1 electrode, and another foot is G pole, use next spark guide connect test method to assume certainly the validity of polarity. Experiment method is like plan institute to show. Receive the pen that bear a watch T1 pole above all, expressing a pen to receive therefore extremely, what measure resistor to should be infinity. Use lead general next T2 pole and G are extremely short receive, be equivalent to giving G pole to be added negative spark signal, what measure T1-T2 right now extremely resistor should be controlled for 10Ω , prove canal of two-way brilliant brake already sparked guide, if pursue (A) place is shown. Will extremely artful with between G pole short receive lead to disconnect, if resistance keeps changeless, explain pipe can maintain on-state on T1→T2 direction.

 

 

Will expressing a pen to receive T1 pole again, the pen that bear a watch receives T2 pole, what measure resistor to also should be infinity, use lead general next T2 pole and G are extremely short receive, be equivalent to giving G pole to be added sparking signal, what measure T1-T2 right now extremely resistor should be controlled for 10Ω , if pursue (B) place is shown. If disconnect T2 pole and G extremely between short receive lead block the cost is fixed, after explaining pipe classics sparks, also can maintain on-state on T2→T1 direction, and have two-way spark function. Afore-mentioned experiments also prove polarity assuming is correct, it is to assume otherwise with not agree with actually, need to be made afresh assume, repeat afore-mentioned measurement process.

 

 

(Two-way brilliant brake is in charge of 2) high-power spark of ability detect

 

Two-way brilliant brake is in charge of small-power spark electric current is lesser, use avometer Rx1 to block what can check a pipe to spark function. Two-way brilliant brake is in charge of high-power spark electric current is bigger, use avometer Rx1 to block again measure Si to cannot make pipe sparks guide. The method that can use plan institute to show for this undertakes metrical, but the power supply that in measuring, needs to use different polarity, with deciding pipe two-way spark ability.

 

 

Brilliant brake is in charge of by many brilliant brake inside tubal module or brilliant brake canal and rectification canal mix composition, voltaic capacity is 25~100A commonly, voltage limits is 400~1600V. It has volume small, weight light, heat sink and circuit height are electric insulation, installation is convenient, impulse withstand wait for a characteristic, basically use at power shift and power control, like all sorts of rectification equipment, make circuit of drive of galvanic all the time machine, without contact optical unit of switch and air.
