I forgot to mention about removing two resistors R134 and R135 from the inverter board. A week ago, an oscilloscope came to me and foolishly hooked its probe to the inverter board and burned the inverter and my PC . I just repaired everything. Batteries should arrive by summer.

I completed the code for my inverter booster control board from Toyota Crown. Implementation on the ATMEGA168PA-AU microcontroller, 16 MHz quartz resonator, code written in assembler. This device is capable of stably maintaining output voltage up to 3.9x the input voltage. Operating frequency PWM 20...

Once I finish debugging the code, I will provide information: where to connect, circuit, firmware and how to control the modification through the inverter’s native interface.

Yes, this is a Toyota Crown (300h) inverter. My Q211 with a power supply of 100V and 3A (300W) spun up to 2400 rpm, when Boost is activated I accelerate the HV to 200V and with the same consumption from the power supply of 300W I spun the gearbox to 3000 rpm, at 170V and 300W to 3200 rpm. I overcloc...

I glued the litl board, soldered the wires, put together a test code (PWM 20 kHz, 50% duty cycle, dead time 1.75 μs) and eventually Boost worked . I think this weekend I’ll update the code to a working version.

Yes the Boost would be very helpful.. if it could be used. Could it be set up for best efficiency or effectiveness in the fwd direction,? There maybe other Q211 users, or trials that have been done. There is one person on a Russian-speaking forum about electric vehicles who has been studying Toyota...

Is the Q211 that I think you are using , as free to turn with no HV power in each direction ? I have one with a " wobbling" output flange on one side, which the mechanic I got it from said was not uncommon. Wonder if something mechanical in the reduction is affecting the higher amp curren...

Did you overcome the directional ,difference fwd and rev, Interested in how this worked out.? I have not yet overcome the difference in forward/backward directions. Part of the solution to the problem is that I give more electrical current when moving backwards. Here is an example: when moving forw...

A few more observations:
Engine power - received revolutions
100V 0.55A 55W - 1050 rpm
50V 2.55A 130W - 1050 rpm
This is precisely why I am so eager to launch the boost DC-DC (Boost Converter) built into the inverter.
And this is my debugging program (Delphi7).

Here is the result of my experiments and observations, if anyone is interested :) . When power is applied to the inverter, I immediately write to it a data packet of 105 bytes in size like this: 16 byte = 4 - complete shutdown of power to transistors MG1, free run-out of the rotor. 42 byte = 4 - com...

Latest merge into the STM32_VCU now allows more power from a 300h gearbox and inverter combination. It was being limited by the fixed values. https://github.com/damienmaguire/Stm32-vcu This is good news! Although I already found the “discharge ability of battery” parameter myself, but thank you ver...

Thank you for your answer, I thought I’d be ignored :) Finding the best option for connecting the phases is not difficult, because there are only three of them. Using a brute force method, I immediately found the correct connection of the phases, but the motor still consumes a little more current in...

Hi all! I bought a Toyota Crown inverter, an L210 gearbox and a Toyota Harrier gear reducer. To begin with, I connected a Toyota Harrier gear reducer to the inverter at home in order to debug the control of the inverter using its native interface. In addition to the parameters and variables specifie...
