Harmonics from non-linear loads increase RMS current through capacitors, causing dielectric failure and overheating. PFC chokes introduce inductive reactance that blocks high-order harmonics from entering the capacitor banks, enhancing thermal performance and extending capacitor service life.
Choke cores are constructed using low-loss CRGO or amorphous materials to handle high-frequency harmonic flux. Magnetic saturation is prevented by maintaining flux density below critical levels. Insulation systems and vacuum varnishing protect against localized heating and acoustic noise.
Inductance is maintained within ±5% to ensure consistent tuning across capacitor stages. Windings are optimized for low AC resistance and thermal stability, supported by thermal analysis to prevent overheating under harmonic-rich conditions.

Frigate calibrates choke inductance precisely to match system requirements, typically detuned to 189 Hz or 210 Hz for 50 Hz grids. Inductance is maintained within ±5% tolerance to prevent resonance mismatch. Design calculations consider short-circuit power, harmonic orders, and system impedance. Each unit is tested under simulated harmonic conditions to verify tuning behavior.
Frigate selects CRGO or amorphous metal cores based on harmonic spectrum and thermal loading profiles. These materials offer low core losses and high magnetic permeability, minimizing eddy current heating under distorted waveforms. Flux density is carefully limited to avoid saturation under transient conditions. Core stacking, air gaps, and lamination geometry are optimized using FEM tools.
Chokes are designed with thermally balanced windings, large surface area, and varnish-impregnated cores for efficient heat dissipation. Frigate performs thermal simulations considering harmonic current levels and ambient rise. Class H insulation ensures dielectric integrity up to 180°C. Optional temperature sensors (NTC/PTC) can be integrated for condition monitoring.
Frigate uses closed-core designs with symmetrical winding placement to reduce stray magnetic fields. Magnetic shielding is applied when chokes are installed near sensitive control circuits. Mechanical damping prevents acoustic noise and vibration-induced resonance. EMI compliance is validated under IEC 61000-6-4 for industrial environments.
Frigate designs power factor correction chokes for voltages ranging from 400V to 690V and can accommodate custom detuning frequencies. Application-specific parameters like harmonic order, capacitor rating, and short-circuit strength are used in the design. Custom inductance values and insulation systems are also supported. Detailed technical drawings and thermal profiles are provided for each configuration.
