DIFFRENTS BETWEEN UPS AND INVERTER

DIFFRENTS BETWEEN UPS AND INVERTER
UPS:
Ups stands for uninterrupted power supply.It provides power supply to load ,when Input power(Mains) is failed(shut-downed), from the energy stored in the battery.it will provide near-instantaneous protection from input power interruptions.Its voltage range will be from 180v to 240v only as its voltage range(interval)is  very less it protects the devices(applicants) connect to it from High voltage or short circuits.



It's  divided into  three  categories 
1.OFFLINE UPS  

2.ONLINE UPS   

3.Line interactive UPS



OFFLINE/STANDBY

  The offline/standby UPS (SPS) offers only the most basic features, providing surge protection and battery backup. The protected equipment is normally connected directly to incoming utility power. When the incoming voltage falls below or rises above a predetermined level the SPS turns on its internal DC-AC inverter circuitry, which is powered from an internal storage battery. 




ONLINE UPS
In an online UPS, the batteries are always connected to the inverter, so that no power transfer switches are necessary. When power loss occurs, the rectifier simply drops out of the circuit and the batteries keep the power steady and unchanged. When power is restored, the rectifier resumes carrying most of the load and begins charging the batteries, though the charging current may be limited to prevent the high-power rectifier from overheating the batteries and boiling off the electrolyte. The main advantage of an on-line UPS is its ability to provide an "electrical firewall" between the incoming utility power and sensitive electronic equipment.

Line-interactive 

The line-interactive UPS is similar in operation to a standby UPS, but with the addition of a multi-tap variable-voltageautotransformer. This is a special type of transformer that can add or subtract powered coils of wire, thereby increasing or decreasing the magnetic field and the output voltage of the transformer. This is also known as a Buck–boost transformer.

INVERTER


Inverter is a electrical device w+hich converts DC current to AC current.It provides power supply to load ,when Input power(Mains) is failed(shut-downed), from the energy stored in the battery.When connected, an inverter allows these devices to provide electric power for small household devices..Its voltage range will be from 140v to 300v as its voltage range(interval)is  very High it can't protects the devices(applicants) connect to it from High voltage or short circuits.

There are two types of inverters

  • Sine wave inverters produce good-quality AC power. They are expensive.
  • modified sine wave inverter produces a lower quality of AC power, with strong power system harmonics but is cheaper. Various modulation strategies are used in cascaded multilevel inverters to reduce the harmonic contents.
