Amorphous Distribution Gap Core - For Ultra-Low Loss Energy Transfer in Renewable Inverters, Precision Medical Imaging, and Defense Electronics

The Amorphous Distribution Gap Core leverages rapid-quenched Fe-based nanocrystalline alloy (thickness: 0.018–0.025mm) with strategically distributed air gaps (0.05–0.3mm). This patent-pending design achieves dual-phase magnetic regulation: amorphous zones deliver near-zero hysteresis loss (<0.05 W/kg @ 10kHz/0.3T), while air gaps provide adjustable permeability (±25%) and suppress DC bias saturation. Optimized for 1kHz–100kHz operations, it enables loss reduction up to 85% vs. silicon steel counterparts.

Ultra-Fast Flux Response

Nanosecond-scale magnetization reversal (<100ns) for PWM frequencies up to 500kHz. Multi-gap flux steering eliminates harmonic distortion under 200A/μs di/dt transients.

Extreme Loss Efficiency

Core loss: 0.8–3.2W/kg @ 20kHz/0.5T (40% lower than best silicon steel). Near-zero eddy currents via <15nm oxide layers and stress-relief annealing.

Thermal & Stability Advantages

Curie temperature >390°C ensures stable μ at 150°C ambient. Vibration resistance: <0.05 ppm magnetostriction under 1.4T excitation.

EMI Immunity

Distributed gaps absorb 90% of RF noise above 30MHz (MIL-STD-461 compliant). Shielding integration reduces stray flux by 18dB.
