My understanding is power conditioner is a device to help and provide a clean power output but not backup power like UPS.
Question: can you UPS do the same thing?
]]f
UPS is basically a device that converts battery DC to AC supply when there is a voltage dip or power interruption. under that heading, a UPS is a conditioning device, as it basically enhances equipment tolerance to voltage sags and blackouts.

Not all UPS designs are what is called "double conversion" like that, some are a Power Conditioner with a battery backup and a single conversion inverter. But even many double-conversion UPS systems have a high current bypass that provides inrush current right around the inverters so that the output transistors are not damaged by high peak loads. When they do that they may not have any power conditioning, other than maybe surge arrestors on the input terminals.]]
You missed a step, a UPS that is a true on line double conversion UPS. Takes AC converts through the rectifier to DC to float charge a battery (and equalize after discharges), then converts through the inverter the DC to AC, this is very good conditioning.
Another type of UPS uses a motor generator with a battery charger for the battery, the motor generator feeds the load, upon lose of power the battery feeds motor through a inverter (GUESSING ON THIS CONVERSION). Also an excellent power conditioner.

This is partially correct. However there are a lot of things that a power conditioner has no effect upon like under voltage, over voltage, frequency variations, momentary interruption, ect. To take it one step further there is no definition of what a power conditioner is. It can be as simple as a TVSS unit that will will only clean up some minor transients and nothing else.My understanding is power conditioner is a device to help and provide a clean power output but not backup power like UPS.
The answer is Yes and No. Like the power conditioner there is no clear definition of what a UPS system is. UPS fall into 3 basic catagoroes:Question: can you UPS do the same thing?
Line Interactive UPS uttility power is not converted directly into DCbut is fed directly to criticl loads through an inductor or transformer. Regulation is continiousthe the load through the use of an inverter via a static switch working in the Buck and Boost feroresonant transformers.
Stand by UPS are the cheap things sold at box stores where the load is entirely powered from the utility input. They are designed for momentary interruption to allow time for the battery and inverter to be switched on line. Pretty much worthless.
They are line interactive. The inverter can boost or buck the output for swells and swags in the line through the magnetic transformer. So In most models the regulation is tighter than what you suggested.Dereck,
Your info is interesting. Good categorization of functions.
Is the Buck and Boost Ferroresonant transformer
the same as a Constant Voltage Transformer,
where the input voltage may vary maybe from 95 to 145 V
and the output voltage varies maybe from 115 to 125 V ?
The one I used was loaded down by a capacitor, had several windings.
I agree with you that the ride through time on a single PC with most everything shut down is the only reason most of these things work. But for the most part they have no filtering or power conditioning except maybe some MOV's or SAD;s for TVSS. Couple that with very crude Modified Sine Wave Inverters just does not cut it in a commercial or business application.Not exactly true. Close all your apps and just leave up a Windows desktop. then pull the computer plug. Notice how there is a pause until it goes off. most switch mode power supplies have at least a few 60hz cycles of ride through. Linear supplies do as well depending on how heavily they are loaded. The standby UPS takes advantage of this dwell time to switch the mechanical relay.
