Pure sine wave and modified sine wave inverters
The inverter come in two types; pure sine wave power type and modified sine wave type. In the
pure sine wave power inverter, the 230V AC output harmonically follows a smooth sine wave
and is almost identical to normal mains electricity. As a result, the pure sine wave output would
be better for most appliances than the modified sine wave output.
A Graphic Comparison of Modified Sine Wave and Pure Sine Wave is shown below:
