I want to put VFDs on a few machines I'm working on, namely a blower that I want to throttle to maintain constant pressure despite filter clogging and baffles opening and closing. It will be a quiet, low speed large diameter airfoil type blower, and I really don't want to listen to VFD whine in the motor the whole time it's running.
Sine wave output inverters are common and affordable in various consumer products where noise is an issue. Is anyone aware of a line of commercial VFDs that produce sine wave output in the 2-10hp range?
I am aware of line reactors but those can whine on their own and an output stage designed for sine wave output is going to be cleaner, easier, and smaller than adding filters.
