UPS (uninterruptible power supply) circuit diagram, in this article you will learn what is UPS? What is the difference between online and offline UPS ? I have also added practical circuit for UPS in this article. uninterruptible power supply have very core importance for control of sensitive devices such as computers, induction machines, medical equipment’s and many other things. uninterruptible power supply also used in many countries where energy shortage is a main issue. In country like Pakistan, many people use UPS in load shedding timings. In such cases, UPS is used to store energy in batteries when main Power supply is available. Same UPS is used to convert DC energy stored in batteries in AC supply to provide power to AC operating equipment’s of homes during load shedding timings. Mainly devices which have severe effect of change in following parameters above and specified limit connect with uninterruptible power supply.

The UPS utilizes multiple EDLC cells in series and the charge voltage is applied across all cells in the series or the stack” of cells. Due to small differences in cell capacitance and “ leakage current, it is possible for one cell to charge to a slightly higher voltage than other cells in the series stack.
- Over voltage
- under voltage
- voltage out
- voltage spikes
- frequency fluctuation of 1%
- distortion in voltage wave form.

UPS uninterruptible power supply is a device used for protection against over voltage, under voltage; provide continuous supply in case of supply outage, protection against voltage spikes, frequency fluctuation and against distortion in voltage wave form. In many cases you must have listen, your home devices burnt out due to over voltage and under voltage. UPS provide protection to these devices. There are many places where outage in main power may damage data permanently. For example in banks or companies where computer should remain on all the time during working hours and outage in main power supply may damage their computers data and which in return loss for a company.In such places UPS provide continuous power to computers. In industries induction machines are used mostly. Induction machines are frequency sensitive loads. Little bit change in frequency produce change in induction motors output. To avoid change in frequency to reach to the input of induction machine UPS is used. Similarly There are many devices which need pure sine wave to operate properly. But in power system use of power converters inject harmonics and voltage wave form distortion in main power supply. In such cases UPS is used to provide pure sine wave to load. But many uninterruptible power supply available in market don’t have a pure sine wave output which cause bad affect on performance of loads. Most important factor is reduction in life time of a device/load. Two types of UPS are mainly used

Introduction to Automatic Inverter / UPS Wiring
Power failure and emergency breakdown may happen any time due to short circuit, damage to electric transmission lines, substations or other parts of the distribution system , storms and other bad weather conditions etc. In this case, emergency generator or battery backup can be used to restored the electric power to the home and other connected appliances. In some case, it is very important to restore the power as soon as possible like in Hospital ICU, military, Intelligence and security systems & offices etc. This is where we use the generator and Inverter / UPS (Uninterruptible Power Supply) system with the help of backup batteries and inverter.
For this purpose, we have to shows an automatic UPS / Inverter system connection and wiring to the home or office supply. We have different tutorials on UPS and Inverters wiring & installations to the home distribution boards such as manual, automatic and inverter / UPS with changeover switches.

Why & Where we Need Auto UPS / Inverter System?
As we have mentioned above that emergency breakdown and power blackout may happen anytime due to a number of reason. In some cases, you may need a continues and uninterruptible power supply to the connected system such as security networks & systems, operation theater & ICU in hospitals, airports, military and intelligence systems and other important electrical networks. In other ordinary cases where you face load-shedding from the power supplier, unavailability of secondary power i.e. generator, solar, wind power etc, low voltages issues, shortage of stored power in the batteries, where you need an uninterruptible power to your home, office, PC, or particular rooms and load points in home or office in case of failure of main power supply. In all those situations, you need an automatic UPS / Inverter wiring connection to the home panel board.

How to Connect a UPS / Inverter to the Home Supply System?
To connect an inverter / UPS to the home electric supply system, follow the steps below:
1kv Ups Circuit Diagram Pdf Online
First of all, disconnect those Live (Line) wires of two circuit breakers from the main distribution board which are connected to the main double pole switch of those particular rooms (As shown in Fig) which you want to connect to the automatic supply (in both cases from battery and main utility power without any interruption).
Suppose, you need to connect only two rooms and their load with UPS automatic system as shown in fig . You will have to disconnect the live wires of these rooms from the main power supply distribution board. Now connect these two live wires (of those specific room which have to be connected to the UPS System) to the output of UPS through the two single pole MCBs (separated from the main panel board). Done.

Keep in mind that only the two connected MCBs (and their related and connected load) to the inverter will supply continues power in case of blackout. To charge the Battery via inverter, connect the Inverter / UPS to the outgoing of main double pole (DP) MCB through a 3 Pin Power Plug and 3 Pin Power socket to the main supply.
Note: To be in safe mode, use 6 AWG (7/064″ or 16mm2) cable and wire size to connect the UPS to the main panel board.

Below is a given UPS Inverter connection and wiring diagram to the home supply. The circuit shows that only two rooms of the home are depends on the UPS and Batteries as well as main supply to maintain the uninterruptible power to the connected appliances and load such as lighting points and fans etc and the other loads are fed up by utility power only. Once you get the basic idea of UPS connection, proceed to know how it works in both cases i.e. operation of the circuit when utility power is available and battery backup as secondary power in case of power failure.

Working Principle & Operation of Automatic UPS / Inverter
1. In case, when the utility power supply is not available:
In case of unavailability of main electric supply, power flow will continue to the particular rooms / office and appliances connected to the UPS system and battery where inverter convert the 12V DC system to Single Phase 230V AC (UK & EU) or 120V AC (US & Canada) voltages according to the specification and ratings.

2. In case, when power supply restores from the power house:
In this case, the main electric lines supplies power to the home appliances in particular connected rooms. Keep in mind that UPS / Inverter will start to charge the battery i.e. it will convert the main Single Phase 230V AC (UK & EU) or 120V AC (US & Canada) voltages into 12V DC to charge the battery for backup storage.
