A power inverter device that produces a multiple step sinusoidal AC waveform is referred to as a sine wave inverter. To more clearly distinguish the inverters with outputs of much less distortion than the modified sine wave (three-step) inverter designs, the manufacturers often use the phrase pure sine wave inverter .
grid-tie inverter A power inverter that allows synchronization with the electrical grid for export of energy surplus to the facility's needs. ground A reference point for electrical potential; often connected to the Earth. ground and neutral Protective and circuit return conductors in a wiring system. ground-level power supply

A modifed sine wave inverter may cause certain types of loads, such as motors, to operate less efficiently than when powered by [alternating current in the form of] a pure sine wave, whether that sine wave be from a "pure sine wave" inverter or regular AC power from the wall outlet.
An inverter represents one of the basic components of a variable speed drive (VSD) that includes other components such as a rectifier, an intermediate circuit and a control unit. The basic work of an inverter within a VSD is simple. A microcontroller integrated with the inverter manages the speed of a motor according to demands.

English: Waveform of an automotive inverter producing 120 V AC, approximately 60 HZ|, from the vehicle's 12 volt cigarette lighter power outlet. This three-step waveform uses alternating positive and negative pulses to approximate the peak to peak and RMS values of a sine wave.
A pure sinusoidal voltage is a conceptual quantity produced by an ideal AC generator built with finely distributed stator and field windings that operate in a uniform magnetic field. Since neither the winding distribution nor the magnetic field are uniform in a working AC machine, voltage waveform distortions are created, and the voltage-time ...
