Active Harmonic Filter (AHF) is a tool for filtering harmonic currents produced by non-linear loads. In addition to compensating for harmonic currents, it can also compensate for reactive power and imbalance. AHF (Active Harmonic Filter) obtains the current signal from the load by CT, separating the harmonics with intelligent FFT (Fast Fourier Transform). DSP (Digital Signal Processing) sends PWM signals to the internal IGBT. AHF will generate compensation current with the same value but opposite phase as system harmonics to achieve real-time dynamic filtering function.
Function : • Reduces THD I to < 5 % • Phase Current Balancing • Reduces Neutral Current • Improve Cos phi / power factor • Improve Power Quality

Active Harmonic Filter (AHF)
Static Var Generator adopts the hardware structure of FPGA, and the components are of high quality. Thermal simulation technology is used for thermal design of the system, and multi-layer PCB circuit board design ensures reliable isolation of high and low voltage, which provides guarantee for system safety.
SVG (Static Var Generator) uses IGBT to control the value and phase of AC voltage of inverter, so as to serve the purpose of reactive and harmonic compensation. SVG can realize fast compensation for reactive load, and achieve very high compensation precision. Our SVG adapts the new technology of 3-level, more reliable and high performance. SVG is currently the best solution in reactive power control filed. SVG is faster (within 10ms), its compensation precision is high (power factor over 0.99), the compensation method is flexible (SVG can compensate both inductive reactive power and capacitive reactive power), and SVG also has the function of active filtration of harmonic current.
