Having Doubts? Our FAQ

Check all our Frequently Asked Question

How does Frigate avoid magnetic saturation in saturable reactor inductors during surge conditions?

Frigate designs saturable reactor inductors using high-grade silicon steel or amorphous cores with tailored saturation flux density. The core geometry and lamination thickness are selected to support magnetic regulation without early saturation. These inductors undergo overload testing to validate flux behavior under transient surges. This ensures consistent operation without magnetic loss under full-load switching cycles. 

What design features support Frigate’s saturable reactors in high-temperature converter environments?

Frigate uses thermally rated insulation systems, Class H or above, and selects cores with low hysteresis loss across elevated temperatures. Coil windings are laid out to enable uniform heat distribution and avoid thermal hotspots. The construction is validated using thermal cycling and endurance tests. This allows reliable performance in enclosures with ambient temperatures up to 130°C. 

How does Frigate maintain controlled saturation behavior in custom reactor configurations?

Frigate tunes the air gap and adjusts core cross-section to define precise magnetic saturation thresholds. This enables engineers to select reactors that act as current limiters under fault conditions. Each design undergoes magnetic modeling to ensure defined knee points on the B-H curve. The result is predictable saturation performance for tightly regulated power circuits. 

Can Frigate’s saturable reactors operate in applications with asymmetric waveform inputs?

Frigate optimizes magnetic path symmetry and balances winding distribution to mitigate waveform distortion effects. The core assembly tolerates offset magnetic bias without flux drift. These reactors are tested using controlled non-sinusoidal input to evaluate response stability. This makes them reliable for systems with waveform imbalance or partial-cycle conduction. 

What factors does Frigate consider for mechanical stability in large saturable reactor builds?

Frigate uses rigid coil support structures and high-strength bobbins to prevent displacement under magnetic stress. Core clamping systems absorb vibration and reduce acoustic noise. The entire assembly is tested for dimensional stability during saturation cycles. This ensures performance reliability during installation and long-duration operation.
