High Frequency Variable Frequency AC Power Supply

VFP-H Series High Frequency AC Power Supply

Overview

High Frequency AC Power Supplies convert AC electric to pure sine waveform by through AC – DC – AC conversion, which is different from variable frequency speed controller and common AC voltage regulator. 

AC Power Supplies are mainly used to convert existing AC power network supply to stable and pure sine power supply with regulated required frequency. The features of ideal AC Power Sources are stable frequency, stable voltage, zero internal resistance and Sine wave form (without distortion). 

High Frequency AC Power Sources are close to the ideal AC Power Supplies , so the developed countries more frequently use Variable Frequency Power Supplies as the standard supply to provide the most excellent powering environment for electrical equipment and to easily evaluate their technical performance. Major types of Variable Frequency AC Power Supplies are: Linear Amplification and PWM Switching. 

VFP-H series High Frequency AC Sources are manufactured under SPWM mode; it is designed by MOSFET module as active component, and adopts other technologies as digital frequency division, D/A conversion, instantaneous feedback and sinusoidal pulse width modulation to make the capacity of single unit up to 150KVA. Isolated transformer used to enhance total stability, strong load applicability, high quality output waveform, and simple operation, small size and light weight. In addition, this power supply has many protective functions against short circuit, over current, over load and over heat to ensure proper operation. 

Comparing to traditional frequency inverter power supplies, our inverter power supplies remove the transformer and frequency converter, by using pure high-frequency conversion technology, with built-in by AC/DC and DC/AC parts, our AC High Frequency Power Supplies could give stable AC output with prefect output precision. 

Because, our new technology does not need transformer for conversion and isolation, the power supplies' size can be reduced within the same output power rating, and not limited by the transformer, output frequency could reach 15 ~ 1Khz continuously adjustable.
