21 Threads found on edaboard.com: Igbt Test Circuit
Currently I am studying the switching characteristics of igbt using Pspice simulation. I downloaded the spice model from manufacturer's website (for example, Infineon and International Rectifier) and used the same dynamic test circuit recommended by the product datasheet. I found many simulation results for switching loss (...)

Has any one tried simulating igbt with PSpice for accurate power loss and switching characteristics under HARD switching conditions?
How accurate the simulation results are?

oh, thanks for ur remind. as to the desaturation diode, i have connected it to the igbt.

I didn't connect the COM to ground because I'll use a Neutral-Point-Clamped arm and I don't want to make a connection between the four igbt emitter.
The ground connection is required.
Please consult the IR2110 application notes about permitted voltage differences between pins.
Besides the required DC path between COM and VSS, t

I need info on how to test igbt. Can it be tested without being removed from PCB?

You can test the igbt by multimeter at the Diode test position.
Emetor Collektor must be open circuit at the two direction (If you see reverse diod this is not problem).
Gate Emetor must be open circuit.
If you see any short circuit at the any two pin igbt is (...)

The BSM15GD60 data sheet can be downloaded from:
As far as in-circuit testing of igbt is concerned, you will be able to test for shorts and free-wheel diodes ..
For a proper test you will have to remove module from the circuit and test each igbt using (...)

I am designing igbt driver. How to select the current rating of Gate driver for particular igbt. What is the criteria. What is the criteria for selecting fast switching diodes across the igbt Driver. I want use the SGP23N60UFD in 3-phase Half Bridge design. Please give me suggestions to select the suitable driver for 3-phase Half (...)

I am asking about some help. I am doing a project wich supposed to oscillating current about 25 kHz. L1 = L2 and i replace l3 with a 100watt lamp. It works. When i change the lamp with an 500 watt lamp( the load will have about 1800watt ). The circuit doesn´t work and blow up the igbt. Any one help me? Why igbt blows up? In both (...)

i will suggest you a test method. in the start-up if your controller makes the dutycycle %100 your igbt will dead and you con not even notice it if it wolud not explose :)
so i make my own tests with a "series lamp" always. there is a picture of it, sorry for bad drawing. but you can test your (...)

I think your mean is that you want to test your igbt ( is intact or not?). if yes, your answer is simple! if you give +15 volts between gate to emitter of your igbt , Its collector , emitter junction , will become short circuit( approximately). if you can see this behavior , your igbt is (...)

mosfets have a tendency to fail closed, while igbts have a tendency to fail OPEN in inverter topology. so i always used igbt.

The curve looks plausible so far. It looks like the igbt is destroyed by the huge overvoltage during emergency switch-off. The only way to reduce the overvoltage are soft switch-off and dynamic clamp. But they don't necessarily work for any load circuit.
I wonder, if this is a realistic short circuit scenario or an artificial (...)

I'm new to the TL494 and i'm using it for a buck converter. So, basically i'm using it for the igbt. I've tried carrying out the circuit given in the datasheets (for tl494) at

Do you just wish to see the output signals?
If so, then, observe output at LO for low side signal. Connect VS to ground and observe output at HO for low side signal. Then remove connection from VS to ground.
This way, you can only observe output signals/pulses.
To figure out if the high side drive is proper or not, you need to connect a MOSFET/IG

Hi guys, we are trying to use ir2113 to drive the igbt for our project. We plan to make an H-bridge using the igbts but we cant drive the igbt using our IC. When we tried placing our PWM as input in the HIN pin of the IC, the HO pin only outputs a straight DC voltage.
When we tried on the LOW side, it worked fine.
Our PWM is 0 to 5V (...)
