What does diode do to use after all in circuit?
[introduction] diode basically can be used in all electronic circuit, its character also is special, basically be only way conductivity most, (sheet brings the resistor cent between the foot to be to two of conductivity mixing to resistor retrorse resistor two kinds) . People uses these different character to make all sorts of specific application circuit, when the diode job principle in analysing different circuit, want to use the different character of diode, choosing the what character of diode to analyse circuit is one of the greatest difficulty, mastered all sorts of character of diode only, ability analyses the working principle of diode circuit leisurely, come to those who use to everybody introduce diode what to do after all in circuit according to product and circuit graph below!
Rectification circuit pursues
This is circuit of complete wave commutate, the VD1 in circuit and VD2 are rectification diode, be to use rectification diode to make rectification circuit in power source circuit, rectification circuit changes alternating voltage into one-way and pulsatile volts d.c. .
Circuit of simple and easy stabilized voltage pursues
The 3 diode VD1 in circuit, VD2 and VD3 make series circuit, they are having the effect of dc stabilized voltage in circuit.
Temperature compensation slant buy circuit graph
This is a kind of special cent is pressed slant buy circuit, diode VD1 is used undertake temperature is compensated, in order to make the work of dynatron VT1 more steady, suffer temperature the impact is less.
Protect circuit plan
The diode VDC in the road uses protective drive 3 class are in charge of VT1. Circuit of this kind of protection in relay drive and electro-magnet suck iron there is wide application in circuit.
Stabilized voltage value adjusts circuit graph
When if the stabilized voltage value of stabilized voltage diode cannot be satisfied,using a requirement, can undertake with common diode stabilized voltage value adjusts, the VD2 in circuit is stabilized voltage diode, VD1 is common diode, VD1 can increase volts d.c. 0.6V.
Switch diode circuit pursues
The VD1 in circuit is switch diode, his action is equivalent to a switch, use put through and disconnect of capacitance C2.
Diode is restricted a circuit graph
Medium diode receives circuit to output signal to make foot and land in integrated circuit A1 after series connection between, constitute pair of output signal be restricted, prevent to output signal too big and the dynatron at the back of attaint.
