Core Composition: Integrates capacitors, composite switches, protection circuitry, and a control system.

Application Environment: Clean power grid environments with very low harmonic content (e.g., THDu < 3%).

Key Value: Provides basic reactive power compensation and improves power factor; replaces traditional discrete components with a modular design.

Core Configuration: Built upon the basic model, it incorporates a reactor with a specific reactance rate (e.g., 7% or 14%) connected in series.

Application Environment: Environments subject to harmonic pollution caused by non-linear loads (such as variable frequency drives, LEDs, and computers).

Key Benefits: Suppresses harmonic amplification, protects capacitors from burnout, and filters out harmonics at specific frequencies.
