Pulsed input currents cause voltage ripple across DC link capacitors, leading to increased ESR losses and capacitor wear. Line air chokes offer inductive smoothing that limits ripple amplitude and controls dI/dt stress. The result is extended capacitor life and improved voltage stability across the DC bus.
Common-mode noise from fast-switching devices induces leakage currents and EMI issues. Balanced winding line chokes present high impedance to common-mode signals while maintaining differential-mode performance. This supports compliance with EMC regulations and reduces ground loop interference.
Load transients can generate voltage spikes that compromise insulation and damage components. Line air chokes limit the voltage rise rate by introducing controlled inductance, absorbing transient energy, and reducing overvoltage risk to semiconductors and DC bus capacitors.

Suppresses inverter-generated harmonics and limits voltage ripple at the DC link in variable frequency drive (VFD) systems.
Provides filtering between rectifier and DC bus, reducing switching noise and protecting DC link capacitors in solar or wind inverters.
Minimizes EMI and ripple currents during AC-DC conversion, ensuring DC bus voltage stability in onboard and offboard EV chargers.
Controls dI/dt and harmonic injection into the DC link, improving performance of fan, compressor, and pump drive systems.
Limits high-frequency noise and transient overshoots across shared DC buses in servo drive and multi-axis motion control systems.
Reduces ripple and transients during charge/discharge cycles, protecting DC bus components in grid-tied and standalone battery systems.
Converters under partial load often operate inefficiently due to unstable current profiles and excess switching. Line air chokes stabilize current flow and reduce switching spikes, improving system efficiency and minimizing losses across a wide load range.
Stable choke performance depends on core material behavior under high frequency and elevated temperatures. Using nanocrystalline or gapped ferrite cores ensures low core loss, minimal inductance drift, and thermal reliability. Class H insulation and vacuum-impregnated windings further support durability in high-stress environments.

Frigate designs chokes using optimized air gap distribution and low-saturation core materials. This prevents inductance drop even under peak current. All designs are validated using non-linear FEA simulations. Stable inductance ensures ripple filtering performance remains consistent across the load cycle.
Frigate conducts high-frequency impedance scans up to 500 kHz to characterize attenuation performance. Each choke is tested for core losses, leakage inductance, and thermal behavior under real switching profiles. Thermal imaging and impulse testing confirm high-frequency noise suppression. These tests ensure compatibility with modern SiC or GaN-based converters.
Frigate uses thermally stable insulation systems rated up to Class H (180°C). Core materials are selected for low hysteresis and eddy current losses. All units are vacuum impregnated to improve heat dissipation and mechanical integrity. This allows operation in high ambient temperatures without derating.
Yes. Frigate evaluates harmonic current spectra and selects core geometry to maintain impedance at critical harmonic frequencies. Design includes proper wire gauge and cooling to handle harmonic RMS current. The result is a choke optimized for 6-pulse, 12-pulse, or 18-pulse front-end systems.
Chokes are mechanically braced to handle magnetic forces during short circuits or inrush events. Frigate uses FEA to simulate stress on winding and core interface. Vacuum impregnation prevents coil movement and insulation wear. This ensures long-term performance even under extreme transient loads.
