The variable frequency power supply converts the AC power in the mains into a pure sine wave through AC→DC→AC conversion, and the output frequency and voltage are adjustable within a certain range. It is different from the variable frequency speed controller used for motor speed regulation, and also different from the ordinary AC voltage stabilized power supply. The characteristics of an ideal AC power supply are stable frequency, stable voltage, zero internal resistance, and a pure sine wave voltage waveform (no distortion). The variable frequency power supply is very close to the ideal AC power supply. Therefore, advanced and developed countries are increasingly using variable frequency power supplies as standard power supplies to provide the best power supply environment for electrical appliances and facilitate objective assessment of the technical performance of electrical appliances. There are two main types of variable frequency power supplies: linear amplification type and SPWM switching type.
