Very funny, Germany's cars don't use Siemens or ABB drive but buying.....Japan Hitachi!!!!!

Germans are not the best in electronics. Taiwan and Japan are.

@@phoneaccount6907 But Germany is the only country, outside the US, who has completeness on IC ecosystem. Germany has its own 32 bit design CPU which uses its own microcode and assembly code. It is not licensed built from US&UK as the whole world industrials did. Germany also has its complete tools in developing any project or works from the chip.

Fantastic teardown dude. Will be watching for more.

wow interesting. Cant believe hitachi supplies audi. I dont think many japanese OEM uses hitachi as their INV suppliers

Please open the switching module too.

Really Informative! Thanks. Keep up your great work.

Superb, More informative. Please do more videos on Body control module, Engine control module also. Thankyou soo much for knowledge sharing.

really interesting thanks for sharing

Awesome video! It would be also interesting to see the evolution of the parts "hidden" from the outsiders.

super genial - i want more

Impressive

Hello fans of Mr. Ichiken and Mr. Ichiken 😀. This Hitachi inverter has already been presented by the host, but in the Japanese version. Full professionalism as usual! The three complex power transistors, or rather their configurations, are very impressive. I counted as many as 14 connections for each of them. Also the Infineon Technologies tri-core processor is very powerful. Mr. Ichiken pointed out the cooling channels and tabs that prevent the wrong assembly of power semiconductors. Like any device, it has the right to break down. I'm curious if it's worth repairing? I thought the simplest thing would be to replace the power transistors. But maybe I'm wrong. I invite fans to my new clip published on KZread. It presents an innovative system of functioning of the Brushless Hybrid Fast - Rotation Motor with complex coils of its own design based on the current of the sine function of two control lines. In the absence of a suitable four-phase inverter, it is powered by a frequency converter with single-phase current. Today I accelerated this mini machine to 300 Hz = 18 kRPM. Regards 😀.

Thank you for the like 😀.

Worthwhile to point out that this inverter does not use the boost-buck circuit* topology in-between the HV battery and the 3-phase drivers as Toyota does (* Boost: battery to IGBT driving motor; Buck: 3-phase rectifiers back to HV battery for charging) Also, A/C compressor's 3-phase HV motor's driver is not in this module.

I don't like Japanese short cut of cables linked both modules it's like less caretaking .

Very thorough examination. It looks complicated, thus many failure points. O-rings don't last forever. It looks expensive to replace. I think it would be more reliable to do away with the many o-rings and cooling ports. Submerse the entire unit in a dielectric. And simply use a heat pump type of cooling.

"Promosm" 😪

Overly complicated and Overengineered

A simpler design would be better for costs, reliability and maintenance and what if those orings fail and coolant leaks inside ? Those custom bus bars look expensive im sure there would be a simpler and cheaper way to design this thing.
