Description

Technical Field

[0001] The utility model relates to the technical field of power supply, in particular to a variable frequency power supply. Background Art

[0002] The variable frequency power supply converts the AC power in the mains into a pure sine wave through AC→DC→AC conversion. 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). There are many battery modules in the variable frequency power supply. When installing the battery module, it is inconvenient to use screws to fix it due to the small space, which affects its installation efficiency. Utility Model Content
