What is the pure sine wave inverter?

Pure sine wave inverter is inverter to ac from final transformation of one class of the waveform classification; another kind is square-wave inverter.What Pure sine wave inverter output is sine wave alternating current that is the same as the grid that use daily with us and even better, because pure sine wave inverter does not exist electromagnetic pollution in the grid.What Square-wave inverter output is lower quality square-wave alternating current?

Compared with the pure sine wave inverter, quare-wave inverter's load ability is poor, cannot take the perceptual load. If it brings too big load,square wave current contains three harmonic compositions that will make the capacitive load current increases and will damage the power load of filter capacitance when seriously. Recently, pure sine wave inverter (or says improved sine wave, correction sine wave, simulated sine wave, etc.) is the latest equipment that is designed for solving this problem.Pure sine wave inverterhave one time intervalsbetween positive maximum output wave to negative maximum. The using effect has been improved, but the sine wave waveformwhich inthepure sine wave inverter is still composed by polyline.It belongs to square-wave category and continuity is bad.

Generally speaking, pure sine wave inverter can provide high quality alternating current, leads to any kind of load, but technical requirements and cost are high. Pure sinewave inverter can satisfy most of our electricity demand withhigh efficiency, low noise; price moderate, thuspure sine wave inverter becomes mainstream products in market.Square-wave inverter uses the simple harmonic oscillator. Its technology belongs to the 1950s level and will gradually withdraw from the market. Pure sine wave inverter will be the best choice of people in the existing technology range.
