A pure sine wave is a smooth, continuous wave that represents the ideal form of alternating current (AC) electricity. It is characterized by its consistent frequency and amplitude, creating a waveform that resembles a sine function. This type of wave is essential for powering sensitive electronic devices, as it provides a stable and clean power supply. In contrast to modified sine waves, which can produce electrical noise and distortions, pure sine waves ensure that devices operate efficiently and without interference. Many inverters designed for solar power systems or backup generators produce pure sine wave output to maintain the performance of appliances like computers and audio equipment.
