Horizontal active filter compensation module

The active filter compensation module is a modular product developed by LiDAR Electric specifically for dynamic harmonic control in 0.4kV power supply systems. Connected in parallel to the power grid system, it uses an external CT to detect the load current in real time. Utilizing DSP/FPGA/CPLD chips, and incorporating the latest fast harmonic control or reactive power extraction technology, it rapidly analyzes the harmonic or reactive power content of the load current. Then, based on the set value, it generates PWM pulses to drive a bidirectional converter comprised of three-level IGBT modules, producing a compensation current that meets grid requirements. Ultimately, it achieves dynamic and precise compensation of harmonic or reactive current, improving power quality.
