Our products have a good price advantage and cover most of the South America, Middle East, Africa, Southeast Asia markets. We look forward to becoming your long-term partner in China.
The theory of instantaneous reactive power of three-phase circuit is the main basic theory for the development of APF. There are two kinds of APF, parallel type and series type, the former is used more; Shunt active power filter mainly deals with current harmonics and series active power filter mainly deals with voltage harmonics. Active filter compared with passive filter, good governance effect, mainly can filter out many times and high harmonics at the same time, will not cause resonance, but the price is relatively high!
