RACTIFIER

DEFINATION THE CIRCUIT WHICH CONVERTS A.C VOLTAGE INTO D.C. VOLTAGE IS CALLED RACTIFIER

TYPES OF RACTIFIER 1.HALF WAVE RACTIFIER 2.FULL WAVE RACTIFIER 3.BRIDGE WAVE RACTIFIER

HALF WAVE RACTIFIER

CONSTRUCTION STEP DOWN TRANSFORMER(AS PER REQUIREMENT), DIODE IN 4001/ PIECE, RESISTOR 1K  -1 NO.

WORKING THIS RACTIFIER CONVERTS HALF A\C VOLTAGE CYCLE INTO D.C VOLTAGE

EXAMPLE IF YOUR TRANSFORMER IS 6V/A.C THEN IT’S OUTPUT YOU GET 3V/D.C

FULL WAVE RACTIFIER

CONSTRUCTION STEP DOWN TRANSFORMER(AS PER REQUIREMENT), DIODE IN 4001/ PIECE, RESISTOR 1K  - 1 NO.

WORKING THIS RACTIFIER CONVERTS FULL A\C VOLTAGE CYCLE INTO D.C VOLTAGE

EXAMPLE IF YOUR TRANSFORMER IS 6V/A.C THEN IT’S OUTPUT YOU GET 6V/D.C

BRIDGE RACTIFIER

CONSTRUCTION STEP DOWN TRANSFORMER(AS PER REQUIREMENT), DIODE IN 4001/ PIECE, RESISTOR 1K  -1 NO.

WORKING THIS RACTIFIER CONVERTS FULL A\C VOLTAGE CYCLE INTO D.C VOLTAGE

EXAMPLE IF YOUR TRANSFORMER IS 12V/A.C THEN IT’S OUTPUT YOU GET 12V/D.C

DIODE

TYPES RACTIFIER DIODE ZENER DIODE LIGHT EMITTING DIODE (L.E.D) DETECTOR DIODE STEEK DIODE VARACTOR DIODE LIQUID CRYSTAL DIODE (L.C.D) PHOTO DIODE TUNNEL DIODE

CONSTRUCTION DIODE IS A CONNECTION OF P & N TYPE SEMI CONDUCTORS. DIODE HAS TWO TERMINAL ONE TERMINAL IS POSITIVE (+) OTHER IS NEGATIVE (-) POSITIVE TERMINAL KNOWN AS ANODE NEGATIVE TERMINAL KNOWN AS CATHODE. DIODE IS MADE FROM SEMI CONDUCTOR MATERIAL LIKE GERMENIUM & SILICON

WORKING OF DIODE RACTIFIER DIODE :- IT CONVERTS A.C VOLTAGE INTO D.C VOLTAGE ZENER DIODE :- IT IS USED FOR VOLTAGE REGULATION L.E.D :- IT IS USED FOR EMITTING LIGHT DETECTOR DIODE :- USED FOR BLOCK HIGH FREQUENCY STEEK DIODE :- USE FOR HIGH VOLTAGE RACTIFICATION ( NEXT PAGE )

VARACTOR DIODE :- USE FOR CHANNEL TUNING L.C.D :- USE FOR DISPLAY DIGITS PHOTO DIODE :- USE FOR CONTROL THE CKT BY LIGHT TUNNEL DIODE :- USE FOR SWITCHING

TRANSISTORS

TYPES OF TRANSISTORS PNP TRANSISTORS NPN TRANSISTORS FIELD EFFECT TRANSISTOR ( F.E.T ) UNI JUNCTION TRANSISTOR ( U.J.T ) SILICON CONTROLLED RACTIFIER ( S.C.R )

CONSTRUCTION TRANISTOR IS A CONNECTION OF TWO DIODES. PNP TRANSISTOR :- N TYPE SEMI CONDUCTOR SANDWICH BETWEEN TWO P TYPE SEMI CONDUCTORS. NPN TRANSISTOR :- P TYPE SEMI CONDUCTOR SANDWICH BETWEEN TWO NTYPE SEMI CONDUCTORS. PNP & NPN TRANSISTOR HAS THREE TERMINAL ( NEXT PAGE )

TERMINALS NAME ARE EMITTER, BASE & COLLECTOR PNP & NPN TRANSISTOR ARE BIPOLAR TRANSISTORS (BJT) TRANSISTOR IS SEMI CONDUCTOR DEVICE TRANSISTOR MAKE FROM SILICON & GERANIUM SEMI CONDUCTOR MATERIAL

FIELD EFFECT TRANSISTOR F.E.T HAS THREE TERMINALS THESE TERMINAL KNOWN AS GATE,DRAIN & SOURCE. F.E.T IS UNI POLAR TRANSISTOR

UNI JUNCTION TRANSISTOR UJT HAS THREE TERMINALS THESE TERMINAL KNOWN AS BASE 1, BASE 2 & EMITTER U.J.T IS UNI POLAR TRANSISTOR

SILICON CONTROLLED RACTIFIER S.C.R HAS THREE TERMINALS THESE TERMINAL KNOWN AS ANODE, CATHODE & GATE S.C.R IS UNI POLAR TRANSISTOR.

WORKING OF TRANSISTOR PNP & NPN TRANSISTOR HAS TWO JUNCTION, EMITTER BASE JUNCTION & COLLECTOR BASE JUNCTION F.E.T,S.C.R,U.J.T HAS ONE JUNCTION CURRENT FLOW IN FROM ONE JUNCTION & DIRECTION

APPLICATION OF TRANSISTOR AMPLIFIER SWITCH CONTROLLED PROCESS

INTEFRATED CIRCUIT MAKE BY MICRO PROCESS USING CKT PHOTOGRAPH. IT IS A FULL CKT MAKE FOR CERTAIN FUNCTION. IT’S FUNCTION & PIN CONNECTION KNOWN BY I.C. NUMBER. I.C HAS THREE OR MORE TERMINALS. FOR FIRST PIN CALCULATION THERE IS MARKING ON I,.C.

CONSTRUCTION OF I.C MANY TRANSISTOR, DIODE,REGISTOR & CAPACITOR INTEGRATE IN I.C. I.C MADE BY SEMI CONDUCTOR MATERIAL LIKE SILICON & GERMENIUM. MADE BY L.S.I,M.S.I,V.L.S.I. TECHNOLOGY

TYPES OF I.C. 1.LINEAR I.C. 2.DIGITAL I.C.

LINEAR I.C. USE FOR AMPLIFIER MODULATOR & VOLTAGE REGULATOR. IT IS BI POLAR MONOLITHYC OR UNI POLAR MONOLITHYC.

DIGITAL I.C. USE FOR MEMORY,LOGIC, FREQUENCY DIVIDER, INVERTOR,COUNTER, DECODER, ADDER,GATE, DATA SELECTION, DISTRIBUTORS.

TESTING & FAULT FINDING OF I.C. DIFFERENT I.C. NUMBER CHECKERS USE FOR I.C. CHECKING. APPLY BY VOLTAGE OR GIVING SIGNAL WE KNOW I.C’S FAULT.
