What is the Difference between off-line and online UPS?
The offline UPS is in standby mode. The charger is maintaining the battery, but the inverter stage is not running. Power goes from input to output, bypassing the inverter. In this configuration, the charger and inverter design is less, as the charger is usually in trickle mode and the inverter does not need to run continuously. On power fail, the inverter starts up and takes the load. There is a glitch in output, a few line cycles, but most loads can handle this. The online UPS runs all the time. The charger now runs the inverter, as well as maintaining charge on the battery. The inverter supplies the load. Power goes from input to charger to inverter to output. In this configuration, the charger and inverter design is more, as they need to run continuously. On power fail, there is no glitch, because the inverter is already running and supplying the load. Usually, there is synchronization between the inverter and the line, so that failure of the inverter can initiate fall-back to the line without glitch.
How does a ups recreate an ac sine wave?
By switching circuits or transistors that turn on and off the polarity. This usually results in a square wave output. Then capacitors charge and discharge to smooth out the square wave to resemble the AC sine wave. The better or more expensive the inverter, the closer to an actual sine wave it gets.
How is an inverter constructed?

What type of current does an uninterrupted power supply use?
Uninterrupted power supply (UPS) is a stand by battery. Charged with mains power, it is designed to give out DC current should the mains power suddenly goes off, long enough for computers to be shut down properly, so avoiding corruption of data and the computer system. I believe that in some larger commercial/military/Government organisations, an inverter DC to AC is in their larger capacity UPS systems, to continue on AC until the mains power is restored.Another AnswerA UPS is often used to supply computers, in order to protect their data in the event of a power failure. They consist, essentially, of a battery charger, a rechargeable battery, and an inverter. The main power supply maintains the charge on a battery, via a battery charger, and the battery's output is converted to an a.c. output via an inverter. Voltage values are maintained by internal transformers.
Working of MOSFET base inverter?
what is the main function of transformer in inverter
Can ups be connected to inverter?
Ups can be connected to an inverter since it does not exceed the rated voltage
WHAT IS THE Difference between an inverter and UPS?
In UPS ,the main power comes to the UPS and is used to charge a battery inside. The output from the battery is fed into a sine wave inverter which converts DC into AC and feeds to the computer in case of a power failure. In such a scenario, the battery is stopped from charging and instantly starts to supply power to the computer. In Inverter ,AC is converted into DC and then is used to charge the battery. When the power supply goes off, the relay triggers the switch from mains to inverter. It is the use of a sensor and a relay that is the main difference between a UPS and an inverter, otherwise the two are same. And the use of relay and sensor cause the time delay in power supply from an inverter.
The major difference between inverter and ups?
An inverter simply takes a DC voltage, usually from a battery, and converts it to AC for use by standard appliances. A UPS does the same thing, but has added circuitry to charge the battery when AC utility power is available, and to automatically switch the inverter on when utility power fails.
How do you design a ups inverter?

What is the main difference between UPS and Inverter?
Inverter is the one which converts DC to AC. UPS is the one which provides you uninterrupted power supply. UPS as a system comprises of converter (converts AC to DC), battery, battery charger circuit and an inverter (converts DC to AC). Inverter is part of UPS.
What is the Working of online ups?
Online UPS on the other hand uses an Inverter which always on to give sine wave AC in the output socket. The incoming AC is first converted into DC by a transformer to charge the battery as well as to give power to the inverter transformer. The inverter transformer converts the DC to AC continuously to power the load. If power fails, the battery backup circuit switches on and takes the load. Online UPS is more efficient than the Offline UPS and uses a "Constant duty Inverter". It also has a "Static bypass" system that transfers the load to the AC power if the inverter system fails. The advantage of the Online UPS is that, it clean up the AC waveform by converting it into DC then reconverting this DC to fresh AC.
Why UPS is not charging on Inverter?
UPS (UNINTERUPTED POWER SUPPLY ) Its charg only AC current (Alternating current). and inverter provide current DC TO AC ( Direct current to Alternating current)
Can you use inverter battery for ups?
yes, i am using microtech 850 UPS with Exide 1500 AH Battery
Can you equip UPS orInverter for Mail server to have 24 hr Backup?
Yes you can use a UPS provided it can supply enough power for the server and you have good battery backup. A inverter is an option but a little bit more complicated, you will need a good battery charger and you have to run the server on the inverter alone, so the inverter will work 24/24 because you can not use mains supply to the server, so it have to be a good quality inverter, preferably a sine wave inverter with a 100% duty cycle, good batteries and a good charger that will supply enough charge to maintain the current draw of the inverter and have reserve to store energy in the batteries for times when the mains is out and the charger can not supply the energy demand.
What is ups unauthorized CBS package charge?
A CBS package charge with UPS is a consignee billing and service charge. You will need to contact UPS and see why you had this charge.
What is the roll of 555timer in an inverter to build an ups?
To provide gating pulse for power electronic switching device in Inverter. It decides frequency of output, hence should be monitored carefully.
What are the Main parts of Ups?
The main parts of UPS (Uninterruptible Power Supply) are the battery, inverter, and rectifier. The battery stores energy, the inverter converts DC power to AC power, and the rectifier converts AC power to DC power to keep the battery charged.
