The most important characteristic of an inverter - that helps to define its functionality and quality - is the waveform of its alternating current output. The AC that the grid supplies comes in a pure sine wave, which is what all AC appliances are designed to use as their input. A smooth variation between directions of current flow that is operating is necessary for the proper functioning of various complex appliances, but for other simpler appliances it doesn't matter. The three types of output wave forms that are available in the market are the following:
