The frequency conversion power supply transforms the alternating current through AC → DC → AC to output
pure sine wave, and the output frequency and voltage can be adjusted in a certain range. It is different from
the variable frequency speed controller used for motor speed regulation and the common AC stabilized voltage
power supply. The ideal AC power supply has the characteristics of stable frequency, stable voltage, zero
internal resistance and pure sine wave (no distortion). Yidi AC variable frequency power supply is in the leading
position in China.
The frequency conversion power supply is very close to the ideal AC power supply. Therefore, more and more
advanced countries use the frequency conversion power supply as the standard power supply, providing the best
power supply environment for the electrical appliances, and facilitating the objective assessment of the technical
performance of the electrical appliances.
