IGBT JUNCTION TEST PROCEDURE
1. Short out G1 to E1 and G2 to E2. With a multimeter set to check diodes, check across the C1-
C2E1 junction. With the (+) probe on C1 and the (-) probe on C2E1, you should see an open
circuit. Switch the probes. You should see a diode drop on the meter.
2. Check across the C2E1-E2 junction. With the (+) probe on C2E1 and the (-) probe on E2, you
should see an open circuit. Switch the probes. You should see a diode drop on the meter.
3. With a 9 volt* battery, connect the (+) terminal to G1 and the (-) terminal to E1. Using your meter
(set to check diodes), should see a diode drop across the C1-C2E1 junction in both directions now.
Connect the (+) terminal to G2 and the (-) terminal to E2. You should see a diode drop across the
C2E1-E2 junction in both directions here as well.
4. If the IGBT passed all of the above tests, the IGBT is good.
* You may be able to use a second multimeter as a voltage source by setting it to check resistance at its
lowest available resistance scale. The (+) probe is the positive side. However, not all meters provide
enough DC voltage for this, and may even give you false readings. A known DC voltage from 8 to 15
volts is recommended instead.

What tool is used to check voltage?
by using a multimeter we can find line voltage.
Why IGBT is better?
IGBT first of all is a hybrid device meaning the combination of two devices; the BJT and the MOSFET. Depending on the application, one can never say an IGBT is better than others. Typically, an IGBT is ideal for high powered, high voltage and high frequency applications
Who invented the igbt?
B. Jayant Baliga
Why IGBT is a voltage control device?
Yes
How do you test a thyristor module using multimeter?
You can check if it is shorted, but without coordinating the gate and anode voltages with the cathode, you cannot test a thyrister (SCR) with a multimeter. Check it out of circuit for shorts, then check the circuit, then test it in operation. Anything more advanced will require an oscilloscope.

How can you check Integrated Circuits with a multimeter?
To check the IC by the multimeter, you have to make sure that the pointer points at the current. You can then connect the multimeter across the check the IC.
How do you know when a wire has current flowing through it?

How do you check household fuses to find out which one is not working?
Use a multimeter set to continuity position and touch one probe from your multimeter to each conductor. If you hear a tone from the multimeter then your fuse is good.
How do you check transistor by multimeter?
a BJT may be tested as two diodes using the ohms scale. a FET cannot be tested with just a multimeter.
What are the used of multimeter?
to check voltage, current , polarity of of material,etc
