Toyota Estima Inverter Teardown & Inspection

[Jora Karandas]

Hi everyone,

Let's thank our forum member Vjkomix for sharing pictures of a Toyota Estima Inverter teardown & inspection. The inverter part # is G92A0-28010.

The nice thing about this car, it has 2 x powertrains:
A) one very similar to Prius Gen3 inverters and
B) an additional 3rd inverter to drive MG3 (rear axle motor).

The whole assembly upside down compared to how it is fitted on the car:

Logic board #F1759-30010, inverter MG1 & MG2, similar to Prius Gen3:

IPM MG1 & MG2, Power Board # F1789-33010:

My guess, buck/boost converter:

The control pcb is soldered to the PM:

Hi pleasant good day
Can anyone say if their is a method of controlling this inverter assembly their is one available in my area atm with the Transaxle but I'm not finding enough information

Can this be controlled via zombie verter
Or a logic board..

Thanks in advance
