Now that the government has made it legal for the power companies to play with AC line frequencies, I am thinking about AC power "regenerators" Plug in in front of your electronics, but instead of the currently advertised "line conditioner" crud at big prices, it actually would "regenerate" power....take the input, and generate a precision 60hz regulated ac output, like a ups under battery power.
I looked into them years ago, but they were very very pricy. Looking into them again.
But I was thinking of a poor man's version. What if you got a pure sinewave output UPS....it generates the sine wave on BATTERY only, during a power problems situation. What if you removed the battery, and connected a DC power supply to the battery terminals, disconnected the UPS from the ac line, and used it off the power supply all the time????????
I know, perhaps, the UPS circuitry was not designed for long term use, but I suppose a higher capacity ups would work? Assuming a higher capacity ups had heavy duty circuitry, not just a bigger battery.
Any thoughts or help would be appreciated.
