Mr. Mindset, I was at work the last couple of days witnessing the atrocities of industrial maintenance mechanics attempting to repair an industrial sized machine. I've watched a lot of your videos and they have contributed immensely to my TH-cam engineering degree. I am not a member of their elite brain-trust, I mostly sit in judgment of them. I rarely read the comments here so I'm not sure if you answer comments but I'm going to try to make this question short. We have a multi-million dollar investment of blow molding machines being installed to replace older style machinery. They have installed a brand new air compressor that was shipped from Germany or Belgium as I recall. We are in the United States. This compressor has been in use for about 8 months now. There have been several failures already of different parts of it; most recently it blew out a seal between two parts of itself that should contain the pressurized air. The brain trust worked on replacing the seal for several hours and then switched it on. I was 100 yards away at the time but I heard an explosion which I imagined was one of the plexiglass sight glasses on it. It turns out it was actually something in the electronics cabinet that so-called controls the compressor. One or more components in the cabinet electrically exploded. It blew the fan out of the side of the cabinet and of course there were a few things scorched and was deemed to require further review before starting it up again. So they spend 12 or more hours the next day working on the cabinet. The whole time the production line is not running and therefore losing money quickly. That's the back story in a nutshell. My real question is why are the electronics important or necessary for a compressor? As I sit in judgment of them I'm thinking about how there was a time before electronics, a time when industry used massive compressors that were simply electric and simply turned on and if they reached their storage capacity a mechanical device would shut them down until demand is greater than supply at which point a mechanical device would trigger the compressor to start up again. I suspect the electronic portion of the compressor's operation is supposed to save energy, and possibly activate oilers, or perhaps purge the air tank on a schedule as a preventative measure. If that's the case then all of those functions could be done without electronics and therefore it seems there would be so much less opportunity for downtime due to overly-complex electronic issues keeping a mechanical device from even running. Sorry it was a long comment but I was thinking all day yesterday that I should ask you on your next video. If you don't respond maybe someone else qualified can offer insight.
The short answer like you mentioned is "cost and energy saving." People in government make the requirements for more "efficient" machinery but don't realize or care that it costs even more to run meticulous circuit board operated machines.
@@UltraGamma25 Thanks for your reply. I hadn't considered that it could be a government regulation. Perhaps it is but my guess is it's more smoke and mirrors than anything. More reason to pay for the technician to come fix it. A side story to the main story is this. A member of the brain-trust said that he thought the explosion was caused by someone not turning off the power at the main panel where the electricity comes into the warehouse. He said they only turned off the electric at the now damaged control cabinet and therefore when they turned the power back on at the control cabinet "all the energy surged through the system and blew it up" So apparently there's a store of energy in the cabinet or the main cabinet that will surge through the system if you don't turn it off at the entrance to the building. However, magically if you turn it off at the compressor the energy does not surge from the entrance to the compressor. The shutoff at the compressor apparently lets the pixies in nice and slow. Somehow I missed the giant battery or capacitor bank that doesn't exist. Not knowing something is one thing but going so far to make up a story is a completely different thing.
How does passing the square wave through a transformer affect the shape of the output wave? Do you get another square wave? Or is there some smoothing of the shape?
Pictures a TV but ironically you would need the inverter to power it as that's the source its been designed to run off but its internally rectifying to dc at around 90v to drive the backlighting and usually 12v and 5v for the rest of the circuitry.

So that’s how a simulated sine wave is produced, but how is a pure sine wave produced like in a UPS from the battery? Is it simply a better grade of switches operating even faster? Or is there something else involved?
I have a unique idea of putting a mini split AC compressor in a car but using car parts (I'll only use the compressor, the evaporator, condenser etc will left stock from the car). I'm planning to get a 0.5hp or 1hp compressor (I might need to upgrade my alternator) and get a 1500w sine wave inverter (or make a custom one myself with EGS002 module so I can integrate things better with the car). This also gives me the opportunity to run my car's AC without turning on my cars engine by using a transfer switch to power it from my house (I do a lot of things in my car) and use a server power supply to power the auxiliary condenser fan, the blower fan and charge the battery at the same time. I'll do this when my Denso 10PA15C dies (i bought it used). What do you guys think?
I think that you should avoid leeching energy from your car, especially from its battery or alternator. You will destroy it prematurely. If you have an old engine you can use it as a back up generator if you know what you're doing.
@@UltraGamma25 I'll upgrade my alternator (or make a dual alternator setup). But I think this will use less energy because my current stock setup can take like 5hp from the crank.. that's a whopping 3750 watts power from its crank. I'll have a spare 10pa15c just in case this experiment failed to work. I don't really care about how complex it would be if it gonna work in the end. I actually have done something similar to my alternator in 2019 when there's a mass blackout in my area. I use my car to power my whole house using a power inverter and it worked just fine
How can one take spiked dc above and below 0, high voltage and high frequency down to 120/240 60hz? Can a pure sine wave inverter do this? If so what is the maximum volts and frequency they can handle? For example 2000 volts to 120/240 can be achieved by calculating wire turns from the L1 side of and using fewer turns on the L2. How does one reduce frequency? Capacitor and resistor in parallel? Or can this be done with an inverter?
but do you even need wave? I always thought it is simply a consequence of the way we produce AC, but not something desirable, that's why 3 phases are considered better so you can smooth out those waves
I have a very difficult time understanding this. I'm very concerned about running my oxygen concentrator when the electricity is down and I have used up my tanks. Can I have a car battery in my house with an inverter, and if so, how long would it last? I hope I get an answer; I'm so worried!!!
_You forgot to mention that electronic devices are also DC, alternating current is only meant for traveling distances. Once you plug your device into an AC wall the power also gets converted into DC. None of the components on the motherboard is alternating current._
Well, alternating current is meant to easily transform between different voltages, as the only thing you need(simplified of course) is some wires wrapped around some iron. Travelling big distances is done best by DC
@@guitar-jo No no, I only meant that travelling long distances is done most efficiently by High Voltage DC. Over long distances capacitance between power lines and between them and ground is getting really big, and with each change od direction which is being done at 100 times per second the energy is wasted on that. In DC you only have to figth that capacitance once when you turn the line on. At the end of a HVDC line you just use inverter to convert it back to AC and distribute it localy
I do not consider this to be true AC, but rather faux AC. You never get a true sine wave. It is always +120v or -120v just turned for varying amounts of time. True AC fluctuates between 0v and +120v and 0v and -120v over the prescribed amount of time.
@@guitar-jo sounds more like you have unstable AC from your power provider and your inverter has a voltage regulator in it to boost your AC during sags.
@@mbell1216 Perhaps, but still not the same as pure AC sine wave. That's why some motors will not run correctly on them. My Subwoofer creates a nasty hum when running off one. Just to name a couple examples.

I LOVE THE WAY YOU PREPARE THIS TEACHING VIDEO.AFTER ALL ,THANK YOU.
How does passing the square wave through a transformer affect the shape of the output wave? Do you get another square wave? Or is there some smoothing of the shape?
This was very fantastic! Now I'd like to know why an AC appliance draws 10x its rated amps from the DC source when using an inverter?
When you step up the voltage from 12V to 120V you will draw 10x the current from the primary side of the transformer.
Thank you very much!
This channel is very informative. Thanks for the video

Can you explain how some inverter can sync AC frequency with other ac source, like grid frequency?
phase detection

when the DC pulses are passed thorugh the inductor on the transformer, it smoothens the electrical output to a sine wave
