Indeed, Indeed!! You are so right.

Very good for the basics of an inverter. Personally I used to startup AC variable speed inverters using SCRs as switches. The trick to using SCRs is the ability to turn them off, which requires a reverse bias. The IGBT came along later. The advantage for them is that they can be turned off by removal of the trigger signal. The advent of the IGBT significantly reduced the cost of the inverter and or AC variable speed drive. Note that all inverters wither AC or DC sourced, have a constant voltage DC Buss dependent on the value of the input voltage.. The DC buss voltage results in a constant Peak to Peak voltage. The pulse width modulation as described in this articular is used to vary both the frequency of the output as well as the output RMS (effective) voltage. When used for variable speed when powering an AC motor, constant torgue is maintained by keeping the ratio of the frequency to the RMS voltage constant. For a 460 VAC to 60 hertz system this ratio is 7.67 V/hz. Once the motor rated speed from a constant voltage/frequency system is reached, the motor speed can still be increased by just increasing the frequency with no further increase in voltage. This is called the constant horsepower range. Their is a limit to this as the torque decreases to a point where the motor will no longer run. An inverter and or AC variable speed drive with a 3 phase output has another advantage in that the motor rotational direction can be reversed by just reversing the phase sequence as controlled by the triggering sequence of the IGBTs.

Had an inverter in the truck for ages. Never knew how it worked. Thanks for the video

I remember learning this in some electronics courses. The Toyota Prius hybrid had been using LARGE IGBT's for it's 3 phase motor. Napa Auto Parts training side had a fantastic course explaining how it all worked and more that was built into the system. Of course this video answers questions much better than the books I've read, and I thank you for this. If anyone is learning about DC to DC and DC to AC inverters and converters. That Napa course will give a lot of info, but this video is the start! I'm assuming people that see this video understand the basic theory that "When magnetic lines of force cut across a conductor, a voltage is induced in the conductor and current (electrons) can flow." Without this "working theory," we'd never have the great electrical and electronics we have now!

You need to watch better channels. AvE, project farm, essential craftsman, etc

I am a retired engineer, worked in telecommunications field, engineering digital central telephone exchanges. Most of exchange equipment powered from 48V batt supply which were charged by rectifiers fed from the Building AC supply. But some equipment in the exchange office needed protected 120VAC ( Terminals , Test equipment, Modems), supplied by inverters mounted on Misc racks.

In building my first electric car, this has been super helpful. I'd like to know more about the current load relationship between source voltage DC into the motor controller vs motor controller output after converted to 3 phase. I can easily get motor specs however I need to spec connections to the battery packs. Most connectors I find are rated at a far lower ampacity than I'm dealing with while utilizing a much larger conductor. 90mm2 vs my 50mm2 that was included with the supplied parts. Thanks again for making these videos very helpful and clearly laid out.

Such a beautiful narration to go with an equally brilliant animation!

Nice explanation and illustrations! That answered questions that I always had about the conversions. Nice job, thanks!

Best video ever. Definitely going into my saved Electrical Theory Playlist.

Great video and explanation. One side note: Sometimes it might be difficult to get hold of a 3-phase inverter or an inverter capable of outputting the amount of power required. Therefore, some manufacturers offers inverters that can be connected in parallel to get more 2 or 3 phases instead of one, or in series to get more power (as in more Amps or Watts), or even combined in parallel and series to get perhaps 3-phases at 32 Amps instead of 3-phases at 16 Amps. But please be aware that only some manufacturers offers these solutions, and also that it is usually required that the inverters can communicate through perhaps a CAN network. Another side note: You mention inverters outputting square vawe AC and modified sine AC. Please aware that there are also som inverters which output "pure" AC; ie. with very few or no ripples and a pattern when viewed on an oscilloscape virtually indentical with what you will get from something like a wall socket. Also, some devices like certain electronics might be unstable or even be damaged if used with square vawe or modified sine AC.

Yes, good advice! Also, for any viewers who don't know, there's one more thing to be aware of as the winter approaches and we face the possibility of power outages, like last winter (2021.) - AC generators (standard gasoline generators.) Be careful about what you plug into a standard AC generator. They too produce a "dirty" square wave. Televisions and any other electronic appliances that have multiple circuits with various voltages inside them will not respond well to regular AC generators. They require an Inverter Generator, which produces AC voltage, then converts it to DC voltage, then inverts it to "clean" AC voltage with a smooth sine wave (as shown in this video.)

The logic of IGBT's are identical to transistors. (Not the mode of operation, but the logic.) Ie, a signal is sent to one pin, thus opening flow in one direction between the other two pins. If you want to understand how IGBT's work, start by looking at how diodes work, and understanding the quantum physics at play there, then go to transistors, then IGBT/MOSFETs.

An explanation on how pure sine wave inverters work would be nice. As i'm understanding this video, this is a modified square wave type inverter?

4:13 Side note: Not all synchronous generators have a permanent magnet in their rotor. Some use a circuit fed with DC instead to produce a steady magnetic field, working as an electromagnet. 4:17 The electrons in the winding don't get pushed just because the magnet has a polarity. If that was true, holding the magnet still should also make the electrons move, since the magnet still has its polarity; but in reality this won't happen. The real reason why the electrons move is because the magnetic field of the magnet (or electromagnet) is _changing,_ thus inducing an EMF in the windings. At 4:37 you explained it correctly. 9:48 Even though the phase is split, it's still just a single phase, since the voltage or current in both live conductors are in phase (or 180° out of phase.) To be considered as two phases you'd need a phase shift between the current in the two live wires, i.e. 90°. Anyways, I understand what you meant to say. ;) 10:13 In general, the coils/windings of the generator aren't inserted 120 physical degrees (A.K.A. mechanical degrees.) In fact, in the generator you showed the angle between two adjacent coils (of different phases) is 360°/6 = 60°. Real generator have more than one winding per phase, so they're inserted at angles much less than 120 mechanical degrees; you can google about Ferrari's theorem. What is true, is the set of three output voltages are 120 electrical degrees shifted.

Youre experiencing the dunning kruger effect* (or however you spell it). Youre going towards the pit of confidence but dont worry after you pass that pit, your confidence will increase with the increase of knowledge. If you dont know about this, i'll try to explain it the way i understand it. they (dunning and kruger) observed how people with different levels of knowledge displayed confidence. People with no knowledge had no confidence, people with (overall) little knowledge had a lot of confidence (i get to explain this a bit later). people with with moderate knowledge had a lot of doubt. And the experts had a lot of confidence. The graph kinda looks like this _/V. As people start learning about something their scope of the overall knowledge starts out small so they believe they have conquered a high percentage of all knowledge to be had. That is until they realize that there is a whole lot more to what they do not know, thats when their confidence start to fall. And it will fall more and more until they have the full scope of the knowledge to be had. Kinda like moving the goal post further and further until it doesnt move anymore. And as they continue to learn, they get closer to the goal and that builds confidence.

computers and controllers are basically calculators, they do these types of calculations way faster when you load a video or play videogames

The best explanation I've had. I only needed this video to understand the entire concept.

In 1960 I was a student at a USAF technical school for weapons mechanics. One day we were introduced to a large, heavy, power-hungry and incredibly loud machine that took large amounts of 28v current and produced a trickle of one-leg-grounded three phase ac for airplanes. They consisted of a dc motor driving an ac generator in one unit. By the time I became an airline aircraft mechanic in 1965, these beasts were being replaced by static (solid state) inverters such as the ones you see explained in this video. But probably, somewhere in the world, an old Convair or two still carries one or more of those screaming power-wasters.

1:23, trying to better understand the concept in order to simulate a UPS system

The part I keep getting stuck at is *smooth* AC. Smoothing to DC with the rectifiers and a cap is fine. But, in inversion we've got PWM chopped to 'Sine-like AC' ... but it's rough. Inductors? Something clever?

But if for some reason we would have to have as perfect sine wave as possible, maybe we could then just run DC motors to generate AC? Definitely noticeable energy losses but it would work and wouldn't differ from power plants. :D
