=============================
An Uninterruptible Power Supply is a device that is used to keep computers and equipment safe when there is a loss, or a significant reduction, in the primary power source.
Once this is detected, the control is transfer over to the batteries, and via an inverter, the batteries DC voltage is converted into AC for the devices.
In reality, it doesn’t have to be computers systems and equipment that are kept alive by UPS. It could be anything from a fish tank, to a foot massager!
We aren’t just talking about plain power outages, lights off, TV off, everything, but we can sometimes get spikes in power where a sudden drop can assure our devices are momentarily powered off, or something known as a brown-out.
The amount of time the UPS can sustain a system for can vary, but it allows the opportunity for the issue to be resolved, or at the very least, allows for the systems to be shut down in a controlled manner.
Since a UPS is a system that uses batteries to power a system should the supply be compromised, we, of course, have batteries and a battery charger.
Since the batteries use DC current and our incoming supply is AC current, we need to convert DC to AC using an inverter.
A UPS provides second-level surge protection, but although it does provide some protection, it should usually be used alongside an adequate Surge Protection Device (SPD) to extend the life of the UPS as well as the attached equipment.
Firstly, and the most common in smaller systems is the Standby or Offline UPS.
The Standby UPS lays in wait for its time to spring into action, and once there is a power failure, it takes control. The Standby UPS tends to be the most cost-effective UPS available.
Next up, we have the Line Interactive UPS. It is very similar to a Standby UPS but with the added ability to regulate voltage automatically.
This means that it monitors the incoming supply and can help out if it detects that the voltage is a bit low, or a spike is causing it to go too high.
It can add or subtract power in this way to make the output to our devices constant!
This type of UPS is particularly useful for the brown-out situation we’ve already mentioned, or power spikes or surges.
Now we have the Online Double Conversion UPS. This type of UPS is efficient as the primary source of power isn't the incoming supply, rather it is the battery power.
So when we have a power outage, there is no transfer switch to close, meaning no time to switch that you can get with the other type of UPSs.
When the incoming supply is ON, the batteries simply charge up. It is called a double-conversion because it converts the AC incoming supply to DC, and then the inverter converts it back to AC for the output.
In general, it ensures a far higher degree of isolation of the load from the irregularities on the mains supply.
These are the most common types of UPS available. Of course, there are other types that fit a particular form or function, but these tend to be for more specialist needs.

lol
Lol Agree
Me also sir
😂😂😂😂
This was so wonderfully explained. I'm so glad for the presence of such videos for free
Glad it was helpful! Thank you very much for sharing.
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
Thanks.
Keep going :)
I've appreciate it !
Great to hear that, Alexandr!

Thanks for your support!
Hi. The video is really good and informative for basic understanding. Kindly share the knowledge about how to size the UPS?
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.
@@realpars Thanks a lot 😊
Just found out this existed. Good to know.
Great to have you here! Happy learning.

Please, feel free to have a browse through our course library to see what topics we cover at the moment. bit.ly/30AVJaR
Feel free to reach back out if you have any further questions. Happy learning!
Super sir
Hello: thanks a lot for your video. Could you please inform if this video is for commercial UPS's and not for Industrial UPS's? Regards.
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.
please cover a video on PDU (power distribution unit) ? please explain the meaning & usage of PDU
Hi Shivon!
Thanks for your comment and your suggestion. I will pass this on to our course developers!
Thanks for sharing and happy learning!
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.
Please Do make a video on wapda inverter and conveter

Nice video i like your videos
Happy to hear that, Shubham!
Useful
Glad to hear that!
A good recommendation from RUclips
Happy learning!
Tq so much
You're very welcome!
some ups have solar panel input (solar charge controller inside) and a generator starter in case blackout is too long.
Veeru nice sir
Thank you, Haja!
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).
That's great 💙💙
Thank you, Michael!
Nice sir !!!
Thank you, Sudeep!
@@realpars sir I request You to make more videos on ELECTRICAL INSTALLATION Topics and on TRANSFORMERS unit
thanks
You're more than welcome!
Thanks*^^*
You are very welcome!
Does it protect against power surges?
hello ....please make a video about (SPPA T 3000) CONTROL system best regards
Hi Derin,
Thanks for the topic suggestion, I will definitely go ahead and forward this to our creator team. Happy learning!
I would like to ask if the battery charger works as the same as the rectifier does converting AC to DC?
Yes. Battery chargers use a rectifier to convert AC to DC, and they have additional circuitry to limit current to the battery charging circuit.
Can you please explain Static switch in UPS. Its construction,its components and its working.
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.
Nice found that in some pc games without ups for competitive i had some mouse lag bought UPS and its gone and i live in new house
good
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.
Double Conversion also has the battery in use 100% of the time, reducing battery life length. Replacement batteries are expensive.
Can you explain power model and capacitor used in UPS
Thanks for your comment and topic suggestion, I will happily go ahead and forward this to our course developers for you.
Sir do u have the video whereby u doing UPS maintenance industrial 🏭 or like 60kva upwards.
I would really appreciate the link
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!
