I'd like to use batteries to power the DC bus, and modify a small VFD to control a larger HP AC induction motor.
Is there any DIY info available about how to "marry" a small VFD to larger capacity output devices? (ie: IGBTs rated for higher voltage/amperage.)
Any help appreciated.
Regards,
rmarotta
