- Harmonic Control
Chokes
Frigate chokes are engineered to handle high-order harmonics generated by power electronics and VFDs, which can harm system efficiency and equipment life. With low core loss and high linearity, they effectively attenuate harmonics up to the 25th order, ensuring IEEE 519 compliance and reduced THD.
- Suppress Voltage Spikes
Frigate Output Chokes control high dv/dt, filter noise, and protect motors from insulation stress and bearing current failures.
- Stabilize Inverter Circuits
Frigate DC-Link Chokes smooth DC current, reduce ripple and RMS load, and protect transformers from overheating and thermal stress.
- Boost Battery Efficiency
Frigate Battery Converter Chokes ensure clean current flow, reduce losses, and support longer battery life in EV and UPS systems.

- Efficient Thermal Management
Thermal Safety in Compact Panels
Chokes designed for space-constrained enclosures utilize high-permeability cores and optimized thermal paths to manage heat dissipation under continuous load. Their construction ensures low acoustic emission by minimizing magnetostriction and suppressing high-frequency electromagnetic noise.
- High-permeability core materials reduce core saturation and heat rise.
- Custom air gap design minimizes hotspot formation during high-load cycles.
- Operates silently under load; eliminates EMI and magnetostriction hum.
- Maintains surface temperature under thermal class limits, even at 150% continuous overload.
- Validated using thermal imaging and long-duration burn-in testing at rated load.

Frigate designs chokes using Class H insulation and thermally optimized cores that handle continuous operation at elevated temperatures. Custom air gaps and low-loss laminations help maintain safe temperature rise even under 150% rated load. We also simulate real-world thermal conditions using FEA tools to validate performance. Each choke is burn-in tested to ensure long-term thermal reliability.
Frigate chokes are designed with tight magnetic coupling and shielded windings to block high-frequency noise. The use of distributed gap cores reduces core resonance, which helps suppress conducted and radiated EMI. Special winding techniques, such as interleaving and foil winding, further reduce stray capacitance. These features make our chokes ideal for VFDs, inverters, and SMPS systems.
Yes, Frigate chokes are engineered to absorb bidirectional energy flow in regenerative drive systems. They maintain consistent inductance during power reversal, avoiding sudden current spikes. The magnetic cores are selected to avoid saturation under reverse flux conditions. This ensures safe energy dissipation without compromising efficiency or stability.
Frigate uses high-saturation flux density materials and precise inductance tuning to suppress 3rd to 25th order harmonics. Our chokes help maintain THD levels below IEEE 519 limits, even in heavily distorted grids. Laminated steel or ferrite cores are chosen based on harmonic spectrum. These chokes reduce transformer stress, protect sensitive electronics, and improve power factor.
Frigate offers compact, high-flux core designs with optimized winding layouts to reduce size without compromising performance. We use finite element analysis to manage electromagnetic forces and thermal distribution in tight spaces. For mobile or aerospace applications, lightweight materials and sealed constructions are available. Every design is tested for dielectric strength, vibration resistance, and inductance accuracy.
