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

[@mikethemouse396]

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

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

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 TH-cam. 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 😀.
