Typical applications for power inverters include:
Portable consumer devices that allow the user to connect a battery, or set of batteries, to the device to produce AC power to run various electrical items such as lights, televisions, kitchen appliances, and power tools.
Use in power generation systems such as electric utility companies or solar generating systems to convert DC power to AC power.
A power inverter device which produces a smooth sinusoidal AC waveform is referred to as a pure sine wave inverter. Pure sine wave is extremely desirable because the vast majority of electric plug in products and appliances are engineered to work well with the standard electric utility power which is a true sine wave.
The term "modified sine wave" has come into use and refers to an output waveform that is a useful rough approximation of a sine wave for power translation purposes. Numerous electronic equipment will operate quite well on modified sine wave power inverter devices, especially any load that is resistive in nature such as a traditional incandescent light bulb.
