High-frequency switching causes EMI that interferes with control systems and communication lines. Filter chokes introduce differential and common-mode impedance to block frequencies from 150 kHz to 30 MHz. Core materials and winding layouts are optimized for low parasitic capacitance and stable high-frequency performance.
Rapid load changes can cause current spikes that saturate the core, leading to non-linear inductance and overheating. Filter chokes are engineered with calculated air gaps and low flux density operation to maintain inductance stability. Saturation-resistant materials support thermal limits up to Class H.
Improper tuning of filter networks leads to harmonic amplification due to resonance. Filter chokes are designed with precise inductance and damping factors to shift resonance points safely away from dominant harmonics. Impedance is modeled to prevent adverse interaction with capacitive elements or grid impedance.

Frigate uses low-flux-density designs with air-gapped cores to prevent early saturation under dynamic load conditions. The cores are selected for high saturation flux density and low hysteresis loss. Each choke is thermally derated to match continuous operation at full rated current. Design validation includes B-H curve analysis and saturation threshold testing.
Frigate applies precision winding layouts to minimize inter-winding capacitance and maximize differential-mode attenuation. High-permeability ferrites or nanocrystalline cores are chosen based on EMI frequency range and thermal constraints. Custom bobbin designs and shielding can be integrated when additional common-mode suppression is needed. Chokes are tested per CISPR standards for radiated and conducted emissions.
Frigate designs its chokes using materials with stable magnetic permeability over a wide temperature range. Inductance is maintained within ±5% from -25°C to 125°C, verified through thermal cycling tests. Core losses and copper losses are separately modeled using FEA tools. This ensures reliable performance in both steady-state and transient conditions.
Frigate calculates choke inductance and Q-factor based on the entire filter network, including upstream and downstream impedances. This prevents resonance peaks that could amplify specific harmonics. For LCL filters, damping resistors or split inductance designs are used to suppress oscillations. Tuning is verified through harmonic impedance simulation and frequency response testing.
Frigate uses compact magnetic core shapes like toroidal and C-core to reduce physical size while maintaining required inductance. High-saturation flux materials allow reduced core cross-section without sacrificing performance. Chokes are thermally optimized using airflow modeling for natural and forced convection. Mounting options include vertical, horizontal, and baseplate-fixed types for space-efficient integration.
