Overview
Emissions And Stack function generator is based on voltage type inverter principle, uses the isolated gate binary transistor to control the value and phase of AC voltage of inverter, to serve the purpose of reactive and harmonic compensation. As the switching frequency of IGBT is very high (dozens of kHz), SVG can realize fast compensation for reactive load, and achieve very high compensation precision. Currently the best solution in reactive power control field. Compared with the traditional represented by the regulation speed is faster (within 5 ms), its compensation precision is high (the power factor is over 0.99), the compensation method is flexible can compensate both inductive reactive power and capacitive reactive power, also has the function of active filtration of harmonic current.
