I'm quite a fan of your video tutorials. But in this one, one point is not entirely correct: double conversion UPS are not the most efficient version, quite the opposite. They offer the best power quality, since there is no interruption at all and the AC is newly generated, so no variations or harmonics from the grid are getting to the equipment. Even the frequency can be corrected or changed from 50 to 60Hz of needed. But this process of double conversion is not the most efficient, since it has permanently the losses of an AC-DC conversion plus the losses of a DC-AC conversion. A UPS with transfer switch has very little loses, as under normal operation no conversion is occurring. But you get all the power quality problems from the grid to the load. And you can not influence the frequency.
Thank you for your comments. You are correct about the differences in efficiency (~96% for line-interactive, ~90% for double-conversion), but this is rarely the decision point for selecting one over the other. As you indicated, there are specific advantages to the double-conversion design, which are necessary in particular applications. Both UPS designs provide efficient operation; >90% efficiency is very good for any electrical device.
Sizing of UPS systems is based on load and required time for supplying backup power. A simple way to do this is to add up the loads (in VA or Watts) of all connected equipment and multiply by 1.2. Then go a UPS manufacturer's website and select a UPS that will output at least the total load that was calculated. Then, decide how many minutes of backup power is required, and select the desired model from the data given by the manufacturer. Most manufacturers can help you do the calculation, and many have "calculators" on their websites.
An ups battery will burn for 3 days non stop if it has a minor problem. So extreme caution should be taken when using them. Similarly big computers. The fire cannot be stopped because it is an electric dc shot circuit. At least 50 metres gaps are required for usage. Any DC system is like that. Some of them can burst to a range of 2 miles. Similarly huge TVs. Don't ask me why again and again.
THe animation shows a dirty sine at the source, and a clean sine at the output. Do all of these UPS types provide a clean sinewave by nature or is that another feature that some UPS devices may or may not provide?
Hello, @PspiralifeTutorials. Thank you for your question. Yes, it should be clear on the output side. All good and industrial UPS devices should provide a clean output power source because they protect expensive devices on the output side. Happy learning from RealPars!
My co-workers at my job let me have a UPS battery like this to hook up my TV, game console, and Blu-Ray player at home for my own personal enjoyments in case the power goes out. I have a TrippLite Internet Office 550VA Ultra-Compact Standby 120V UPS, and got me wondering how long it lasts when the power goes down.
Thanks for your comment and topic suggestion! We don't have a video covering that at the moment, but I will happily pass this on to our course developers. Thanks again for sharing and happy learning!
The concepts shown in the video apply to commercial and industrial UPS systems. The main difference is in size and capacity of the batteries and switching systems. Commercial office and home UPS systems are typically 1-phase whereas industrial UPS systems are typically 3-phase devices.
While the UPS is on-line, either on main or battery power, the static switch is in ‘Load On UPS’ state, connecting the inverter output of the UPS to the load. However, if a UPS fault should develop, causing either the voltage or frequency at the inverter output to exceed acceptable levels or an overload , the static switch changes over without power interruption to ‘Load on Bypass’. The circuitry is all sold-state, with voltage and current comparators determining the health of the UPS output. The static switch fails over to bypass power if a problem internally to the UPS is detected by these circuits.
@@realpars You've left a LOT out. He asked how it works. Lot's of UPS use different methods. Some fully rated solid state, some a mix of contactors and partially rated SCRS. You've not mentioned the two pairs of SCRS, (usually), or much else.
do standby USPs provide any additional protection from surges, voltage drops and instable supply for the load, in other words, could it be used as a protection means?
Hi Hamza, Thank you for your question. Yes, it can. But UPS power, depending on your load, will be limited until the batteries die. Regular UPS for backup use at home will last about 30 minutes. Many date servers have more significant UPS that can last as much as 2 hours. Those types of systems have a generator to back up the UPS.
@@realpars my question is about the case where the standby UPS is standing by, and the power is coming from the mains and not the battery, does the standby UPS provide any protection in this case?
As we stated in our video, you can have more than one UPS as a backup in your data center, protecting your data servers. The transfer switch is normally used on the AC side with generators and the utility power line coming into your plant. You can have more than one generator in parallel, too, depending on your engineering design and risk factors of power loss.

The battery charger shown in the video is a rectifier (definition of a battery charger). Thank you for pointing that out, as other readers may find this information useful!
Pls inform do we need to keep ups switch on from switch board( switch off from powwer button) all the time even when we are not working on computer. Keeping switch on all the time affects internal part as ups get little hot. UPS ( APC BACK 600 IN).
Hello, @joshuachu2445. Thank you for your question. Yes, you can, provided your extension cord meets the wattage requirements as your UPS's spec sheet requires. Ensure you stay within the length needed in the UPS manual and your local electrical codes. Happy learning from REALPARS!

I just realized that all cell phones and laptops are technically a UPS since it allows uninterrupted switching between battery and incoming power.
No they are not. A ups supply AC power to another piece of equipment.
No they are not, at all
I work on these and this is exactly how I explain how they work... it's the concept
@@bonesredlight You're probably the only person in the comments that isn't 12 explaining how things work.
@@tramp2892 Same concept, when laptop battery is full it automatically switch to DC on plug and when plug is off it switches to battery AC
GREAT EXPLANATION TAKES LOT OF TIME TO MAKE A INFORMATIVE VIDEO SO THAT EVERY ONE CAN UNDERSTAND

Its act as a backup power system, its reduce power fluctuations.
