Overview

3-Phase Variable-frequency power supply

Product Details

　Introduction

　　Variable frequency power source outputs the alternating current of utility power as the pure sine wave by means of AC→DC→AC conversion. The output frequency and voltage are adjustable within a certain range. AC power source is different from AC speed regulating controller used for motor speed regulation and common AC voltage stabilized power source.
The ideal AC power source features stabilized frequency, stabilized voltage, zero internal resistance and pure sine wave voltage waveform (no distortion). Variable frequency power source is very close to ideal AC power source. Therefore, the developed countries tend to use the variable frequency power source as the standard power source, so as to provide the electric devices the most excellent power-supplying environment, which is convenient to objectively test technical performance of the electric devices. The variable frequency power source mainly consists of two types: Linear Amplifying and SPWM Switching.
