I started working with IGBTs in the late 1990s... they were expensive, about $150 each directly from a sales rep with IR. We were designing a switch mode power supply for a 12Kw UV lamp operating at about 20Khz. we started with FETs but none could handle the current and switching speed we needed. So we transitioned to IGBTs. needless to say we went though about 4 of these a week as the driver would sometimes fail causing the 2 IGBTs (used in a push pull configuration) we were using to short against the 450V DC supply. When we perfected the circuit design. these IGBTs ran very efficient.
This is a great introduction to IGBTs, well done. So few people talk about such weird creatures as hedgehog snake offspring. A lot of this sound familiar, like an application note. ;)
Your informationabout timings confirm my clues, thanks! (each ns electricity pulse travels 33cm more or less, coil winding make this speed slower depending on the motor so it can be matched with the winding length by choosing the right mosfets, and faster mosfets means also higher efficiency ones )
More people should watch this video before saying "MOSFETs solve everything" and forgetting there are other types of power transistors that may work better in a given circuit. It has become a joke to anwser any semiconductor problem with "mosfet".
There is some problem in algorithm, I watch your videos regularly but last 2 videos were not recommended to me... I have manually searched to see why you are not uploading, then got 2 videos unwatched.
Very nice and accurate explanation! But could you send me seeds or a sappling of those IGBT trees that apparently grow in your region? ;) It is really annoying that I have to by my IGBTs.
Sir, In my country... A turned on switch (in this case the transistor) is a closed switch. At 1:52 and many other places you mention a turned on transistor or a transistor that is in the state of conduction , as a open transistor... It it ment to be like that ??
He uses "open" to mean conducting and "closed" to mean non-conducting. To be honest it confused me for a second. A lot of Russian speaking electronics engineers say it the same way, it must be a local language thing.
I thought for a bit and came to the conclusion that it was a matter of representation. This makes sense if you imagine a gate inside a transistor. In the "open" state, the gate passes current through itself. And these gate can also be partially opened, which will reduce the passage of current (which is impossible with a switch).
Excellent video, as a user of silicon carbide, I have been trying to understand why anyone would use an IGBT since the turn on/off energy is so high. I had suspected that IGBT's predated silicon carbide so thank you for the background.
@@illbeyourmonster1959 in my application, the turn on/off energy matters. I think IGBT also become very inefficient below 1 MHz whereas SiC channels are still very low impedance.
@@chrisfuller1268 Pretty much all IGBT applications I work with are power switching done in the 100Khz or less range where they are handling 600 VDC or less rail voltages at 10's to 100's of amps of current.
@@chrisfuller1268 They are typically built into the blocks themselves so it's a non-issue. Most of what I work with are either singles, half bridge or 3 phase full bridge 1200 volt 200 to 600 amp rated power bricks of one design or another. Well worth looking up the specs if you have never ventured into the industrial application side of power electronics switching devices before.
0:52 I think your diagram at the bottom is an SCR or something like that, not an IGBT. Once the transistors are opened in it, they keep each other on and the current can't be stopped by the gate. It stays latched until the current stops for some other reason and it resets.
Very nice interesting information Respactabile Sir Frome Pakistan Karachi Clifton Gizri Muhammad Khalid khan Thanks a lot,s Respactabile Sir I appreciate for you Sir
Channel resistance is higher than silicon carbide? Part costs less, but the inefficiency causes more energy cost to the end user by many orders of magnitude.
Fantastic explanation, thanks a lot, have been long looking for that perspective on how to explain things, you really seem to care, that your audience gets the message(/knowledge) !!! 3:43 A small question: Do they also have something like Hfe (DC current gain), or if not, what is the average minimum/least current needed to switch an average igbt on ??? I have found some PWM-signal-generators that out-put solely 30mA, and I want to know if that can turn-on an average igbt (considering that all other factorsare hosen such, that they are sufficient, thus not-bottlenecking the process...). Sorry if the question sounds too simple, I know by now, igbts are voltage-driven, but isn´t there any minimum-driving-current-demands at all??? I cannot judge it, since I know very little about electronics. Thanks

Nice to know how they work. Last year my induction cooktop died and I was suspecting one of those igbt's died. I opened it up carefully but couldn't determine which one or if any other components where broken. Luckily it was still in warranty and one of the controller boards was replaced. I think many electronics are fixable but requires measuring, diagnosis and of course soldering. 🫤

Hi, this was a great video, I have recentley begun to repair solar and motor inverters, this was a much needed Information.
Regarding IGBTs in the household, I think incudction cooktops use them to drive the induction coils.
Good job man love u from India Punjab Amritsar

It seems the only reason to use an IGBT over a silicon carbide FET is cost?
IIRC SiC FETs are also very ESD sensitive.
This is what I needed to see today
This video is superb. Explanation of IGBTs is spot on. All the mysteries are revealed.
Thank you for all the useful information👍
Very well done & instructive video. Thanks

Current flows through channel. A channel allows current when it's open and stops the current when it is closed. Hope.that helps.
@@sbybill3271 This logic can't be applied for a fuse...
@@akhilvinayak5832 A blown fuse is a closed channel and a working one is open channel. See it works for fuse as well :)

Compared to the loads they can handle their I/O power consumption is a non-issue.

I wonder how one of these would do in a single ended class A audio amplifier?
APT10090 can handle 1kV 12A , they are quite fast enough to operate at 10MHz，that's a special MOSFET , its also cheap 😂

Why do you call a closed switch an "open" channel? I find it a little confusing.

just a small comment: dont say IGBT Transistor. the T in IGBT is already Transistor
What ARE, not what is. It's not singular to type "transistors".
Integrated gay bi trans transistor. We're doomed, we're doomed.
I read that as LGBT transistors.
Ha!
How about LGBT Transgenders?
No free lunch

The letters of the alphabet have different walues, none of which have anything to do with transistor woltages.
It's always bothered me when americans pronounce "Soldering" as "Sodering". That L gets left out in the cold (or is that cod?)
Polar transistor is wrong translation for FET
