Thanks. I vaguely recall that now you mention it

I think all he did was connect the HV battery at the wrong end of the bus. Correct polarity though.

Reminds me of the video Damien did on his Gen3? inverter after the capacitor exploded

I guess the MG2 path would have a higher inductance than MG1

You might know more than me, but I was thinking voltage spike also.

Just a thought: If it is that, and if the rising and falling edges of the PWM waveform are to stay the same then a lower PWM frequency might not make any difference.

What's the failure mode of the IGBTs?

Thankyou for your sacrifice! Looks like this'll be a hard learnt lesson once it's solved.

Do you have an oscilloscope? I wonder if it could be caught in action

I'm going to be getting myself a second pair of axle stands for testing before I take it out on the road
The brake discs could do with a clean up anyway

I say, that's a rare swap!

Ahh that makes sense. Whereas I guess FOC on AC motors allows that hurdle to be overcome

I put this together last night. I came across the data here and thought it would be interesting to have it visualised. It shows the same series-wound DC motor with different constant voltages applied. I was surprised to see DC motor power curves peak and then drop off as the speed increases. I had a...

Thanks SuperV8. I've brushed up on Weber's Toyota series. I'll add their Tesla videos to my watch list too.

It occured to me that maybe, given that somebody (sorry I forget who) on here demonstrated that the Prius Gen3 inverter is current limited to 1000A per phase, the next best option for this pre-packed DC motor controller might be a Yaris(/Auris/Prius C) given it's similarity in build to the Gen3 and ...

Hi, I've been following along with your youtube channels for a little while while gathering info for my EV conversion. I came across a PDF (attached) which seems to originate from Wroclaw University, Poland. On page 11 it tables the power and torque characteristics of MG1 and MG2 of the 2nd Gen Priu...

The Toyota Yaris Hybrid is renamed Prius C in the US, or Toyota Aqua in Japan.

The sloped top allows it to fit in the small engine bay

Thank you all for your patience and help. Eric Soneson Nevermind the inverter power MG1/MG2 PWM output for the moment, have you checked that the controller is outputting PWM corresponding to your accelerator input? I've just come by this thread and I'm keen to help out where I can to find a difinit...
