Correction of Xian Bo:Generally only a simple rectangle wave processing,the general output is a rectangular wave,rectangular waves can not be completely normal with a dynamic load of electrical appliances,there will be no start,hingh heat,abnormal noise,over current,breakdown and other phenom-ena,and may burn the inverter.
Pure sine wave:
The sine wave putput waveform is good,the distortion is very low,and the output waveform is basically the same as the AC waveform of the power grid.The interference of the precision equipment is small,the noise is low,and it can perfectly carry the dynamic load electrecity.
