This reminds me of one time taking ana anatomy class where we took apart a cat. We never got it working again 🙂. I suspect that is the same story here.

I'm an electrical engineer that does this professionally. I must say that I love your videos and will share them with our junior engineers. I'd like a dozen more engineers like you!

I can tell, this man is very proud of his country. :)

Thats a very clearly explained content. I am currently working AS Testing engineer for inverters by VW. What u have explained Made clear Sense to me and i really enjoyed IT.

Dude this was great…Thank you so much! I Subscribed to both of your channels. I found you by accident by searching for inverter teardowns. You remind me of the KZfaq channel “diode gone wild“. Both of you are very good at teaching and explaining things so clearly! This is literally one of the best explanations I’ve seen for electronics on KZfaq. I my own lab and do electronics repair as my full-time job. I focus mostly on component level board repair for industrial clients. Manufacturing machines, circuit boards that come out of robots and CNC machines… Stuff like that. I specialize in test equipment repair, Calibration, and other metrology tasks. But other types of electronics and equipment… I don’t understand very well. So I was curious and I’m so glad I found your video! Now I understand it much better

Thank you so much for this video. I could never afford to tear apart one of these..

I would think the resistor you said prevents discharge is, on the contrary, a bleeder resistor. Its function being to discharge the capacitor when power is removed, so preventing high voltage remaining for an extended time period.

Thank you for a very informative and well presented run down. Well done.

Super nice presentation. Thank you for making tbis video. Best regards!

Thank you for your explanation

I just received a postcard from Prius about problems with the2012-2017 Prius V Class Action Settlement. I like my Prius V and the money it has saved me in gas over the 2012 when it was purchased. After reading the post card, I wanted to look up what an IPM or inverter was. My dad worked on cars since he was 12 and was a mechanic up unto his passing in 2009. I like knowing about the parts of a car. Thank you for a very well made video and explanation of this detailed complex part.

Thanks for your explaination

great .Thank you so much.

Great video bro

Excellent! Thank you.

Great Lecture, Thanks alot. Can you do a video, analysing the Boost chopper and the control circuit that maintains the output voltage in the 3rd/4th generation of the Prius. Would be interesting to watch this

Brilliant . Very informative and useful information. Now I know more than most autoelectricians

very educative. Thank you regards

Wow 😯 Thank you so much for all the detail knowledge that you shared with us , also thank you translator for taking the time to help with understand this great Tutorial. You guys are amazing!

pretty neat how its made to handle all that power i bet similar to locomotives

Wow 🤩 Thank U so much

Thank you!

Great video

Superb video

Very well done to do this in English thank you.

good work

Wow.....fascinating!!

Absolutely love this video, just FYI because I am studying for my L3 ASE and watched your video to understand these components, I think you are mixing up terms. DC-DC Converter uses a step-down transformer to reduce high voltage DC power to low voltage DC power for 12 volt systems like headlights, blower motors and such, hence the "DC-DC Converter", terminology. The big coils are a seperate component called the "boost converter", due to this component inducing lower DC voltage to higher AC voltage to help the MG(Motor Generator's) required load from a smaller battery on HEV's vs PHEV & EV's. On that note, I also am trying to be an engineer so if I am incorrect on anything let me know, open to learning everywhere possible.

THANKS FROM AUSTRALIA

Wow. That is an amazing inverter !! THANK YOU FOR THE VIDEO! I had expected that 90% of the space would be giant igbts or mosfets… but it is only a small portion Where does it connect to the electronic control unit?

Wow! Always wondered why there was two cooling system vs one cooling system. Never thought that the engine coolant may be too hot for the inverter. That’s smart….

vraiment très intéressant. J'aurais aimé voir le schéma de principe général de l'inverter.

感謝しております

Weird english translation for the 136kOhm resistor that goes along with the capacitor. "resistor is there to halt any discharge from the capacitor" should have been "the resistor is there to bleed the capacitor from its remaining charge in order to avoid accidental electrocution when handled/installed/removed".

Beautiful ❤️👍

Would be a really frcking awesome if that inverter could be modified to act as an audio amplifier :) I wonder how hard that would be? Perhaps class D with proper drivers? or hybrid amp with tubes, they like high voltage :)

It’s unbelievable Prius only costs less than $30k

Interesting video. So now I now what inside the converter in my car. 👍

Hello, I am using one of these to build an electric car in the US, I am wondering if you happen to have any of the boards that control the DC/DC converter around, I damaged mine and am trying to find new ones.

I'm subscribing thanks 😊 ☺

Hi, I have a new Prius AWD 2022 with the inverter occupying the spare tire space at the rear compartment. I wonder if it's ok to shift this inverter to the left/right by modifying the foam supporting the base cargo booth. Anything that I should know for shifting this inverter so my tire donut can go in. Thank you.

Sei un grande

I wonder what the optimal, and range of, waveforms are for the MG's? Thanks for sharing! Neat to see some are making use of these in other useful ways. I'd like to try making a welder and plasma cutter from as well as the H-bridge control for upgrading older generators to being better pure sine wave inverter designs. Such a waste crushing, cutting and remelting when all the time, resources, mass and energy made such beautiful works are science and engineering with plenty of math to inductively calculate the designs requirements and system holistically.

Dr.Yuu do you play piano?!....😂😂😂.

I think you got the current transformer windings the wrong way round. The primary is thick, one turn to carry the measured current. The secondary is multiple turns and the current in it is reduced by the turns ratio. The secondary should connect to a very low ohms resistor, the voltage across which is proportional to the primary current. This voltage would then go to the control circuitry.

Thanks so much for this teardown video. It's really hard to find detailed content like this. I have to ask about something you said, due to a component that looks to me like something other than what you've described. Sorry, I have no experience in automotive electronics. Those two coils you pointed to around 6:30 and said were inductors in some kind of DC-DC voltage change, either step up or step down, looked to me more like this may be a transformer somewhere on the AC part of the inverter. Do you know? I'm very interested to find out. Is there a transformer somewhere downstream of the inverter and before an MG set? Do the buck or boost choppers just need very large inductors? If you have some sort of block diagram describing the function and power flow of the prius inverter that would be very interesting. I can't seem to find it. Not even the Haynes manual describes it.

Can any of these components be repurposed? can those huge power transistors be repurposed for amplification? Audio or RF? G7VFY

hello. I need to buy a inverter toyota prius you can tell where buy it. Thank alot

Ouch you wouldn't want to have that fail, I'll bet its only available as a complete module

What is the purpose of inductor

I have a Toyota Prius 2011 .the igbt of the inverter is damaged. I want to order the part .do you know the part number ?

Not bad. Now give one to Big Clive, or Dave (EEVBLOG) Jones, so that they can do a REAL teardown and reverse engineer one.

This looks like an older Toyota inverter. The new ones, at least here in Canada, are thankfully smaller now. These are heavy pieces of equipment.

Men who enginereed this were awesome

I hopened my broken Auris inverter G9200-47190 (equal to the one here presented) before looking to your video. I made your same mistake and failure to the capacitor!!!! :-) Good explanation yours !!

That isnot grease bro, it is thermal paste. Also it is like a big water cooler, nothing special. Imo you dont need two seperate cooling systems, you can just send the cold water to inverter than to the engine. The only fascinating thing i see here is high viscosity gel there. It looks yummy. 😁

So you blow one IGBT and you have to replace the whole converter???

so its not serviceable??

Thankt a lot for the video. Very informative. I do enjoy your content. Just one tip... get rid of whoever dubbed this video. The translation comes around rather cringy a times (especially the "y'all"). In the videos where you speak yourself, you come across as very professional. But it's clear, whoever does the voice-over has no clue about electronics and no motivation to do a good job. I personally think, just subtitles are more than sufficient. But if you still want a voice-over, get someone else. Your content is just too valuable to stain it with awkward voice-over.

日本語動画ありますか？

Damaged the unit because we did not do our homework or follow a manual. This guy is nothing more than a hacker guessing what to do and how anything works.

I got a headache 😖

If you're going to make a video with an audio, make sure there isn't another audio going at the same time👎👎👎
