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 else can I help you with?
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
What tool is used to check voltage?
by using a multimeter we can find line voltage.
Why IGBT is a voltage control device?
Yes
Who invented the igbt?

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 to check frequency with a multimeter?
To check frequency with a multimeter, set the multimeter to the frequency measurement mode. Connect the probes to the circuit or signal you want to measure. The multimeter will display the frequency in hertz (Hz) on the screen.

How can I use a multimeter to check the frequency in hertz (Hz) of an electrical signal?
To check the frequency of an electrical signal using a multimeter, set the multimeter to the frequency measurement mode. Connect the multimeter probes to the signal source, ensuring proper polarity. The multimeter will display the frequency in hertz (Hz) on the screen.
How can I check the resistance in a wire?
To check the resistance in a wire, you can use a multimeter. Set the multimeter to the resistance (ohms) setting, then touch the probes to each end of the wire. The multimeter will display the resistance measurement in ohms.
How do you know when a wire has current flowing through it?

How to check an AC capacitor with a multimeter?
To check an AC capacitor with a multimeter, set the multimeter to the capacitance setting. Disconnect the capacitor from the circuit and touch the multimeter leads to the capacitor terminals. The multimeter should display a reading close to the capacitor's rated capacitance. If the reading is significantly lower or higher, the capacitor may be faulty and in need of replacement.
How can I use a multimeter to check for power in a circuit?
To check for power in a circuit using a multimeter, set the multimeter to the voltage setting, connect the black probe to the ground and the red probe to the positive terminal of the circuit, and read the voltage displayed on the multimeter. This will show if there is power flowing through the circuit.
How do you use a multimeter to check for power in a circuit?
To check for power in a circuit using a multimeter, set the multimeter to the voltage setting, connect the black probe to the ground and the red probe to the live wire, and read the voltage displayed on the multimeter. Make sure the circuit is turned on and be cautious of electrical hazards.
