Is square wave inverter harmful to electronic devices?
Depends on the device. For instance almost all laptop power supplies use a international (aka universal) switch mode power supply. They don't care about modified sine wave output at all! Almost all low-cost inverters use a step-wave output that approximates a RMS sine wave (like wall voltage). This is a double square wave with a gap between the negative going and positive going squares. The inverter companies call this "modified sine" which is kind of a misnomer used as a marketing term. The more expensive inverters use a high-frequency Class-D amplifier to produce a more accurate approximation of a sine wave. It's usually not "pure", as it has some amount of harmonic distortion, but for marketing reasons they try to distinguish their product from the "modified-sine" by using the "pure sine" misnomer. The front end of all switch-mode power supplies rectify the incoming AC into DC as a first step in conversion. Step wave rectifies just as well as a normal sine wave! The ONLY reason to run "pure sine" inverters is if you are running sensitive audio gear with linear power supplies, as step-wave will induce a buzzing noise in the audio signals whereas the smoother approximation will not. Don't believe the hype that the "pure sine" inverter companies promote, it simply isn't true. The only things that are dangerous to run on step-wave are things with triac devices or capacitor-based power supplies. This includes things like Dewalt power tool chargers, light dimmers, etc. If it's extremely light (feels like there's nothing in it), and/or it has a 120V rating only, then it's probably not safe for step-wave use. Dewalt chargers have been known to fail and overheat on step-wave! If your power supply has a wide input voltage, such as almost all laptop supplies (100-240v), it is a universal switch mode supply and therefore safe. This includes most small electronics chargers, like for phones, iPods and cameras. If the voltage requirement reads only 120V and it's NOT a heavy "wall-wart" type supply, it's probably not safe. Check your nameplates! If your device has sound such as a TV or Stereo and it emits a buzzing sound out of it's speaker when you run it on step-wave, then that's not harmful, but is an annoying side-effect. You can buy the more expensive "pure-sine" model if this is undesirable.
Will an ac unit run on modified sine wave?
The unit should run OK on a modified sine wave since motors are not that sensitive to the waveform. Efficiency might be slightly reduced.The real problem may be in starting the unit. If the input does not have enough power to allow the compressor to start properly and it stays running on the start winding, it could burn up the start winding. Checking the current input with a clamp-on style amp-meter should show if it is drawing excess current by running on the start winding.

Operation of an inverter?
An inverter generally changes DC to AC DC current is rapidly switched in polarity across a transformer by hi current solid state switches. The secondary of the transformer steps up the voltage and this output is conditioned to remove excess noise. The output is more like a squarewave than a sinewave, but acceptable to many lo tech devices. There are many details, but this is the basic inverter. More $$$ and you get cleaner AC, and even sine waves.
Can a person use a transformer to convert modified sine wave into pure sine wave for off grids electrical suppy system?
A pure sine wave does not have any harmonic components beyond the fundamental. A transformer, if chosen carefully, could act as a low pass filter (removing the harmonics), but this is overkill. It would be better to develop a filter to do this.
Is there a device that converts modified sine wave AC output from a generator to pure sine wave AC?
Well, a pure sine wave can only be produced as a pure sine wave. If it was modified to begin with, it would never be a pure sine wave. However, an actual generator should be supplying pure sine wave output, while something such as an inverter would be producing a modified sine wave.
Should I Buy a Modified or Pure Sine Wave Inverter?
Many people are unsure of the differences between a modified or pure sine wave inverter. Think of a modified sine wave inverter as a set of stairs. You will get power in blocks and there will be times when the output is sketchy. A pure sine wave inverter provides power much like the power provided by an electric company. Pure inverters provide smoother and more reliable power waves than a modified inverter. A modified inverter is less expensive and can run smaller items, such as a coffee maker or microwave. However, you may want to consider investing in a pure inverter if you want to run larger items, like a computer or television. Electronics that tend to draw a lot of power should always be run on a sine wave inverter for consistency and safety.
What is the difference between pure sine wave and modified sine waves?
A pure sine wave has energy at only one frequency.Any other wave shape has energy at other frequencies in addition to the frequency of the obvious waveshape.If you add up enough sine waves with the right frtequencoies and amplitudes, they'll add up to form any shapeyou want, even a squarewave.
What size of inverter do you need to run a mini refrigerator or a typical bar refrigerator?
for modified sine wave inverter (most common type, if it doesn't say than it's modified sine) a safe bet would be the 1,000 watt inverters or higher because the mini fridge will surge 3-5 times its continuous rated wattage for anywhere from 1-10 seconds. so although your fridge only needs 90-150 watts to run it might burn out an inverter say in the 150-300 watt range. a modified sine wave 1,000 watt inverter is about $65-100. you are supposed to buy pure sine wave inverters for a fridge, but those are expensive. you do run the risk of ruining the fridge faster if you do not run pure sine wave , however.
Why isn't the current coming out of a transformer not a sine function?
The voltage of a transformer should be a sine wave but if the transformer is overloaded with excess voltage there could be nonlinear effects in the magnetic core that cause harmonics (i.e. departure from a sine wave) in the voltage. The current is determined by the load. If the load is resistive the current and voltage have the same waveform (by Ohm's law) but if the load is nonlinear, a diode rectifier for example, the current will depart from being a sine wave.
How do you convert sine to sq?
There is no sensible conversion.
What happen if you give square wave instead of sine wave to the transformer?
If a square wave is used instead of a sine wave in a transformer, the output power will operate at a different frequency. This will produces varying levels of voltage and amperage based on the wave.
What will happen if a modified sine wave inverter with 115 Volts output is used as a power source wherein a step up transformer is plugged into it to get a power output of 220 Volts?
It will work, but the transformer will not be able to supply its full rated load, because of the harmonic distortion of the non-sine wave output of the inverter. The transformer will also probably run a little hotter too. If you are talking a small load fed from a transformer much larger than required, probably nothing to worry about. But if the power level is large, or you are loading the transformer to more than 30 or 40% of its rated VA, you could run in to trouble. Monitor voltages and temperatures carefully (and have a fire extenguisher handy...)
What is the rms voltage for 144 volts modified sine wave?
if that 144 is the peak voltage if its a sine wave the rms voltage is that voltage divided by sqrt(2) if not a sine wave (modified) you must find the area under the curve by integrating a cycle of that wave shape (root mean squared)

What are the differences between multilevel inverters?
Inverters convert DC power into AC power through waves called either sine waves or modified sine waves. Sine waves are the waves that are typically found in power from a power plant. Modified sine waves are made to simulate sine waves. Inverters with modified sine waves work well for backup power in houses and are much less expensive. Although there are several types of inverters, all standard inverters use only one switch, or in other words, one power circuit. Multilevel inverters are a a source of high power, often used in industrial applications and can use either sine or modified sine waves. Instead of using one converter to convert an AC current into a DC current, a multilevel inverter uses a series of semiconductor power converters (usually two to three) thus generating higher voltage. While with an inverter you would transfer energy with the flip of one switch, with a multilevel inverter you would have to flip several switches, each switch requiring a circuit. These multiple switches and circuits usually make multilevel inverters more expensive than inverters.
