So I did the obvious: hook up a 40V battery to the Prius Gen2 DC input, run the boost converter to give us about 300V DC and then run two phases at 50 Hz to give us 230V AC. Feed all that through a filter and run your appliances on it
I tried:
- an 850W coffee machine - check
- a jigsaw - check
- angle grinder - check
The most drop was caused by the coffee machine, 210V but I think thats because the battery pack couldn't keep up. The DC bus is PI controlled while AC is not controlled.
Video coming soon.
This is running on a Prius Gen2 board as is. To run it on a Gen3 Prius board you'd need to wire the buck/boost converter to the STM32.
The point is obvious: you can use MG2 to run your motor and MG1 to run your power tools. Or to make coffee.
I will change to layout to have TIM4 run the boost converter and therefor have TIM1 available to also make 3-phase AC.
I understand correctly, there is no ready-made file.bin or .hex in order to turn an inverter (leaf gen 2 for example) into 220 ac from a high-voltage battery?
