Surge protectors etc
Yea, I know that there were threads in the past (and I may have even started one) but technology changes. Saw this CHART of systems and started thinking. In my 2 trips I never used a protector and ...

What is a VFD?
A Variable Frequency Drive (VFD) is a type of motor controller that drives an electric motor by varying the frequency and voltage supplied to the electric motor. Other names for a VFD are variable speed drive, adjustable speed drive, adjustable frequency drive, AC drive, microdrive, and inverter.
Frequency (or hertz) is directly related to the motor’s speed (RPMs). In other words, the faster the frequency, the faster the RPMs go. If an application does not require an electric motor to run at full speed, the VFD can be used to ramp down the frequency and voltage to meet the requirements of the electric motor’s load. As the application’s motor speed requirements change, the VFD can simply turn up or down the motor speed to meet the speed requirement.

I did not delve further into it. Sounds more like varying frequency than voltage? We need something that automatically adjusts voltage as incoming voltage changes. We want close to 120 VAC and we want something that raises or lowers voltage automatically as needed. And we need something that does not cost a fortune. Can we get more info on whether one of these fits our needs?
