Frequency power supply transforms the alternating current of market cable from the path AC-DC-AC, exporting pure e output and adjustable frequency and voltage within the specific limits. It is different from frequency variable controller in speed regulator of electromotor and any ordinary AC power supply. Frequency variable power supply approaches ideal AC power supply, which has the character of stable frequency, stable voltage, zero-inner- resistance, and pure sinusoidal wave output (without distortion). So it is more and more popular in the advanced developed countries that frequency variable power supplies are used as the standard supplies in order to offer excellent power supply situations and it is easy to examine the technical features of the electric apparatus objectively.
