CVCF & Purified AC Power Source

Overview

The ever-increasing use of non-liner electrical and electronic devices or apparatus has caused great harmonics to power grid which affect the normal work of sensitive-loads or even cause damage, especially for sensitive load. To solve these kinds of power quality issues, the most effective way is to adopt purified AC power source which work with load in series and controlled by DSP like a controlled power source when it works. Its core part is IGBT controlled by PWM. It outputs power of pure sine wave and supply power for connected load. This kind of purified AC power source, also called power quality controller, can solve voltage flickering, voltage sag issues and deal with unbalanced voltage (L-N). In this way, it can supply power of pure wave and balanced voltage to connected load. Our purified AC Power source is widely used in telecom industry, geological exploration, medical industry, railway and mining industry where it need supply good quality power.
