I want to construct test bench for igbt switching test. I will model the igbt component using the measurement data on later. It is my first trial to make PCB with components I buy. I think the basic schematic circuit is below. 112011 Target igbt model is IKP10N60T Infineon, (...)
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
Hi, 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 can anyone share how the test inputs (pin 3 and 4) work? and is there a difference in
hello. i recently in the process of the igbt short protection. but i meet with a little problem. my igbt driver CANNT protect the igbt when the igbt is in the short circuit condition. i use the VLA500-01 driver which is from isahaya, and the igbt module is CM1400DU-24NF. the attachment is (...)
oh, thanks for ur remind. as to the desaturation diode, i have connected it to the igbt.
mosfets have a tendency to fail closed, while igbts have a tendency to fail OPEN in inverter topology. so i always used igbt.
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?
Hey Gentleman! Hi 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 (...)
hi, 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 (...)
Hi all, I need info on how to test igbt. Can it be tested without being removed from PCB? Rgds
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 (...)
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 (...)
