What is a true sine wave inverter? I’m a beginner in electronics, looking for detailed answer.

The following is a good article on choosing an uninterruptible power supply. http://en.wikipedia.org/wiki/Uninterruptible_power_supply#Choosing_a_UPS The article states Quote: If the UPS needs to be quiet when running from battery, or will power AC motors (as found in air conditioners and fans) or other equipment requiring a clean sine wave (such as high-end computer power supplies), a UPS that outputs a smooth sine wave is needed. For PCs and other common electronics, a quasi-sine wave waveform[3] is acceptable An inverter works basically by switching the d-c voltage and applying it alternately in the forward direction for one half cycle, then the reverse direction for the other half cycle. The result is a square wave. The square wave is then filtered to smooth it out and make it look more like a sine wave. The better the filtering the more it looks like a "true" sine wave.
