Active Harmonic Filter

The active filtering compensation module is a modular product developed by Lightdar Electric specifically for dynamic harmonic control in 0.4kV power supply systems. It is connected in parallel to the power grid system and uses an external CT to detect the load current in real time. Using DSP/FPGA/CPLD chips, along with the latest fast harmonic control or reactive power extraction technology, it quickly analyzes the harmonic or reactive power content of the load current. Then, according to the set value, it generates PWM pulses to drive a bidirectional converter composed of three-level IGBT modules, generating a compensation current that meets the grid requirements. This ultimately achieves dynamic and precise compensation of harmonic current or reactive current, improving power quality. Active modular power quality products include: Static Var Generator (SVG), three-phase imbalance controller (ASVG), and Active Power Filter (APF) three types of modular products.
