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!

[@davidhull2030]

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.

[@ericrawson2909]

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.

[@Skracken]

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

[@user-oc2tk5my9t]

There is a good reason for that...

[@waltherrathenau7716]

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.

[@hullinstruments]

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 KZbin 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 KZbin. 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

[@eugeneleroux1842]

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

Thanks for your explaination

[@susiebenson]

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.

[@obianujunwizu7143]

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

[@d2sfavs]

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

[@noseefood1943]

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

[@CeasarBergonia]

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….

[@robertoguerra5375]

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?

[@khaledzaitoun7321]

Beautiful ❤️👍

[@michaelbarnes96]

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.

[@stanley84pl]

I I would like to know how is it working with out copastors for DC Bus. I like your video.

[@zet0korp]

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".

[@wilsonri]

Yeah, I got that too. But my 2024 corolla hybrid won't go. It left us on the side of the road 3 times so far waiting for a tow. The most recent Toyota mechanic noticed that a computer part, (maybe this exact one), is delivering 20 volts to the 12 battery. That can't be good.

[@wimschoenmakers5463]

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

[@RocRizzo]

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

[@campbellmorrison8540]

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

[@abklhayy844]

Men who enginereed this were awesome

[@ericrawson2909]

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.

[@ericrawson2909]

Edit: Maybe it isn't a current transformer at all. You mention 12V, and maybe it is the transformer which is used on the output side of a switch mode power supply to generate the 12V DC supply. That makes more sense. Especially as a current transformer would not have a tapping point on the primary winding. In this case you did get primary and secondary the right way round.

[@aeonikus1]

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 :)

[@embertrowbridge5629]

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.

[@jafinch78]

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.

[@jafinch78]

Interesting compared to the more contained modules in the Gen2 design. Guessing for better temperature control and reducing costs paradigms of design thinking were used for the Gen3. I'm not an expert at this and more a novice. Really awesome and almost scary the EV desperate mentality of many compared to PHEV or HEV designs more logical implementation and approach.

[@dawi9118]

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.

[@adelavalles6314]

Dr.Yuu do you play piano?!....😂😂😂.

[@b1_ferg]

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.

[@RocRizzo]

Third generation.

[@josephmcconnell7310]

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.

[@MTG_Music]

The Oak Ridge National Laboratory did an evaluation of the system here: info.ornl.gov/sites/publications/files/pub26762.pdf Additionally, you might be able to find info on this through the Weber Auto youtube channel.

[@josephmcconnell7310]

@@MTG_Music Wow! Thanks for this. I'll read through it and see what I can learn.

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

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. 😁

[@bikkiikun]

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.

[@davenone7312]

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.
