Input chokes provide a first-order damping effect against steep voltage transients and line notches caused by switching operations, capacitor bank switching, or grid disturbances. The choke’s impedance introduces a delay in current rise time, thereby mitigating transient-induced overvoltages across rectifier diodes and input capacitors. This function ensures lower peak reverse voltage (PRV) across semiconductor junctions, significantly reducing the risk of device overstress or dielectric breakdown.
When capacitive loads such as DC link capacitors are energized, input chokes limit the initial inrush current by controlling the rate of current buildup. The inductive element acts as a series impedance, shaping the charging profile and preventing instantaneous current spikes that may otherwise trip protection devices or cause thermal stress on components. Proper choke sizing ensures compliance with upstream breaker and fuse characteristics during energization.
Differential-mode noise resulting from high-frequency switching converters propagates back through the line and interferes with nearby systems. Input chokes present a high impedance to high-frequency components, attenuating conducted emissions in the 150 kHz to 30 MHz band. Their effectiveness in reducing differential noise contributes to EMC compliance per CISPR 11/22 Class A and B standards, especially in installations lacking active filtering or shielded cables.

Improves electromagnetic compatibility, suppresses line noise, and stabilizes supply current under rapid load switching conditions.
Limits input current distortion from compressor drives and ensures compliance with EN/IEC harmonics standards in building systems.
Provides current filtering to prevent drive faults caused by back-fed harmonics and transient disturbances from regenerative loads.
High magnetizing current peaks during load transitions can saturate improperly sized inductors, leading to loss of inductive reactance and core heating. Input chokes designed with low-flux density and high-permeability core materials maintain linear inductance under full load and transient overload conditions. Air-gap optimization and core cross-section sizing prevent saturation, preserving functional integrity across the entire operating range.
Continuous operation in high-temperature environments demands magnetic components with controlled thermal rise and insulation integrity. Input chokes constructed with Class H or N insulation systems, low-loss laminated or powder cores, and optimized winding configurations exhibit minimal temperature rise even under continuous rated current. Surface temperature stabilization ensures long-term performance without thermal runaway in sealed enclosures or compact panel systems.

Frigate designs input chokes with optimized core material and air gap to maintain stable inductance under rapid current rise conditions. This controls di/dt and limits current spikes that stress semiconductors. The winding geometry minimizes leakage inductance while ensuring thermal stability. These chokes are tested under switching transients to verify dynamic performance.
Frigate chokes are engineered to provide high differential-mode impedance across 150 kHz–30 MHz frequency range. This reduces EMI conducted back into the AC line from switching devices. Each choke is tested per CISPR 11/22 standards to verify emission compliance. The coil design and core selection target minimum high-frequency loss.
Frigate uses high-permeability core materials with low flux density operation and precision air-gapped laminations. This allows the choke to maintain inductance during peak load surges. Thermal modeling ensures no hot spots under overload. Each unit is tested for saturation under maximum current to ensure consistent magnetic behavior.
Frigate offers three-phase input chokes with matched inductance tolerance across all phases. This ensures current symmetry and suppresses imbalance-induced circulating currents.
