Now days UPS is basic usage commodity like Refrigerator, fan,Tv & Washing Machine.In this modern trend to run smooth life  we need  Secured clean power supply without any interruption. In this aspect some Standard brand Like Exide invertersMicrotek Inverter and Luminous Inverter are giving very good quality Inverter products.

Inverter means in  Technical Terms its Converts Ac Voltage to Dc Voltage when need the Battery charge, This process called as Converter method meanwhile if connected load need Ac Power Supply then its start converting Dc Voltage to Ac Voltage this Process called as a Inverter method. this both Conversion and Inversion whole process running automatically running inside the one Device thats called as a Inverter/UPS.

Inverter means in  General  Terms The Device is Supply Ac Supply to Connected Load Continously,If Sometime Failure Ac Supply the device byself give Ac Supply from the help connected Batteries, this whole process doing Device called a UPS

Some Technical Word Explanation While Using UPS

Input voltage

A typical power inverter device or circuit requires a relatively stable DC power source capable of supplying enough current for the intended power demands of the system. The input voltage depends on the design and purpose of the inverter. Examples include:

  • 12 V DC, for smaller consumer and commercial inverters that typically run from a rechargeable 12 V lead acid battery .
  • 24, 36 and 48 V DC, which are common standards for home energy systems.
  • 200 to 400 V DC, when power is from photovoltaic solar panels.
  • 300 to 450 V DC, when power is from electric vehicle battery packs in vehicle-to-grid systems.

Square wave

Square wave

This is one of the simplest waveforms an inverter design can produce and is best suited to low-sensitivity applications such as lighting and heating. Square wave output can produce “humming” when connected to audio equipment and is generally unsuitable for sensitive electronics.

Sine wave

Sine wave

A power inverter device which produces a multiple step sinusoidal AC waveform is referred to as a sine wave inverter. To more clearly distinguish the inverters with outputs of much less distortion than the modified sine wave (three step) inverter designs, the manufacturers often use the phrase pure sine wave inverter. Almost all consumer grade inverters that are sold as a “pure sine wave inverter” do not produce a smooth sine wave output at all, just a less choppy output than the square wave (two step) and modified sine wave (three step) inverters. However, this is not critical for most electronics as they deal with the output quite well.

Where power inverter devices substitute for standard line power, a sine wave output is desirable because many electrical products are engineered to work best with a sine wave AC power source. The standard electric utility provides a sine wave, typically with minor imperfections but sometimes with significant distortion.

Sine wave inverters with more than three steps in the wave output are more complex and have significantly higher cost than a modified sine wave, with only three steps, or square wave (one step) types of the same power handling. Switch-mode power supply (SMPS) devices, such as personal computers or DVD players, function on modified sine wave power. AC motors directly operated on non-sinusoidal power may produce extra heat, may have different speed-torque characteristics, or may produce more audible noise than when running on sinusoidal power.

Output voltage

The AC output voltage of a power inverter is often regulated to be the same as the grid line voltage, typically 120 or 240 VAC at the distribution level, even when there are changes in the load that the inverter is driving. This allows the inverter to power numerous devices designed for standard line power.

Some inverters also allow selectable or continuously variable output voltages.

Output power

A power inverter will often have an overall power rating expressed in watts or kilowatts. This describes the power that will be available to the device the inverter is driving and, indirectly, the power that will be needed from the DC source. Smaller popular consumer and commercial devices designed to mimic line power typically range from 150 to 3000 watts.

Not all inverter applications are solely or primarily concerned with power delivery; in some cases the frequency and or waveform properties are used by the follow-on circ
