Thanks, this helped me identify defective thyristors in welding machines.

Good afternoon engineer. I loved your video. Thanks to him I was able to get out of a problem with a Haas brand module., 🎩

In the real world its not working. But when I put the Emitter as -ve and Collecor as +ve it works

Hello. would recommend apply voltage with the battery to test the SCRs while they are still mounted on a soft starter ???. or is this done only when SCr is been removed ??? are you familiar on how to do voltage drop test to verify contactors health on soft starter??? I been told there is formula to calculate the expected milli volt reading , but cant find much info.

Question: isn't it possible, when testing high voltage IGBTs, that the multimeter may not have enough voltage to test if the component is failing at higher voltages?

@electrotec7113 5 ай бұрын

Yes, most people don't have access to that testing equipment. These tests will work for 9 out of 10 failures though. I've tested a lot of bad IGBTs over the years, and this shows a failure in almost all instances.

hello and congratulations, I have a question, I often deal with 24 to 80 V DC-powered handling systems driven by SCRs of 200-300 A and above managed by the relevant logic/controller. Let's assume that I have an anomaly elsewhere and the SCRs don't come into operation, how can I energize them manually to test them without dismantling them? Let me explain better, the systems control motors, if these do not turn usually the technician energized the first SCR to make them turn, the second SCR which charged a capacitor and then a third SCR which with a sort of countercurrent turned off the first (usually they are disk st333 as in the video, by doing so he was certain that all the power was ok, and he could move on to troubleshooting the auxiliary part, the driving, safety devices etc., therefore what voltage and polarity should I give to the gates always taking into account that some machines are powered by 24v, others by 48, others by 80 and so on. Thank you.

Hi Gentleman, its very nice, rms is an equivalent of dc for ac. could you please explain which one we need to consider in applications: avg peak rms? could you please give me some examples ?

Thank you very much. The book said "make sure you understand why?" But didn't explain shit lol, you solved my question and now I can move on to the next circuit. Appreciate it 👍🎉

Is 1.6meg ohms to low on the SCR anode to cathode? The new ones we have are 20 meg ohms

Esse tipo de explicação é difícil de intender. Primeiro ponto, está movimentar demasiadamente o vídeo. Segundo ponto, veja se pode decifrar a tua língua em outras como português. Estou muito preocupado com isso.

I'm not into electronics, and I'm sure I'm wrong , but, why the load is not better connected on the emitter side? It is more intuitive to control a load providing it with power than to sinking one of his connectors. Is it disadvantageous or is it not possible?
