7 Lab Ethics 11 8 Safety measure 12 9 Exp: 1-Study the characteristics of SCR and observe the terminal configuration, Measure the breakdown voltage, latching and holding current. Plot V-I characteristics. 10 Exp: 2 Perform experiment on triggering circuits for SCR. i.e. R-. Electronics Lab Manual Volume 1 K. A. Navas, M Tech www.doorway.rusor, ECE Dept. College of Engineering Trivandrum Thiruvananthapuram kanavas@redi www.doorway.ru •If, we just reverse the diode to measure the I-V characteristics, the sudden change might destroy the diode. •The diode should not be short-circuited. That will allow a flow of huge current which might destroy the diode. •Current must not pass through it for a .

Power Electronics Lab Manual: 4th semester(ETT) 5 EXPERIMENT No- 2 OBJECTIVE: Performance of DIAC. EQUIPMENT REQUIRED: Trainer kit, Patch cards, Multimeters. THEORY: The other bidirectional operated member of thyristor family is DIAC or diode for alternating current or bilateral diode switch. The DIAC is a five layers. Characteristics of DIAC and TRIAC LAB: 08 LAB: 0 8 Characteristics of DIAC and TRIAC Learning Objectives: 1) Sudy the IVcharacteristics of DIAC. 2) Understand differnet modes of operation of TRIAC. 3) Sudy the IVcharacteristics of TRIAC. Procedure: Diac Characteristics: The connections are made as shown in the circuit diagram. First DIAC is connected in forward direction The input supply is increased in step by step by varying the RPS The corresponding ammeter and voltmeter readings are noted and tabulated. Then the DIAC is connected in reverse condition.

Static characteristics of SCR and DIAC. 2. EXPERIMENT 2(b) VI -CHARACTERISTICS OF IGBT AIM: To plot the VI Characteristics of IGBT. Next: · LED Circuit Design - How to design LED circuits · How do DIAC and TRIAC Work? (Internal Structure, Equivalent Circuit, VI Characteristics. The DIAC is two terminal device exhibiting characteristics generally similar 5) Repeat the experiment for different values of VDS draw the graph of ID.
