Harmonic filter

A.Function

*Reduces harmonic currents generated by industrial inverters and nonlinear loads, improving power quality

*Minimizes thermal and electrical stress on transformers, cables, and electrical equipment

*Enhances system stability and reliable operation

B.Differentiation

*Optimized L1 and L2 reactor design for their respective filtering functions

*Customized L1, L2, and capacitor (C) design based on load capacity, harmonic characteristics, and system conditions

*In-house reactor design and manufacturing for optimized filter performance

*Approximately 20% lighter and 30% more compact than conventional designs

C.Key Advantages

*Designed to achieve THD-I of 5% or less

*High-durability capacitors suitable for harmonic current conditions

*Foil winding with optimized thermal and insulation design for enhanced durability and reliability

*Fully integrated in-house capability from design and manufacturing to testing

D. Structure

*Consists of L1 Reactor + Capacitor Bank (C) + L2 Reactor

*L1: Suppresses grid-side harmonic currents and current fluctuations

*C: Forms a resonant circuit with the reactors to reduce targeted harmonics

*L2: Suppresses high-frequency components from the load/inverter side

*Optimized L1–C–L2 combination ensures effective harmonic reduction and system stability
