Core performance indicators

1.0 - 1.6 T

High saturation flux density (Bs) and excellent resistance to DC saturation reduce inductor size.

Soft saturation characteristics

Distributed air gap design improving system safety.

Low loss performance

Optimized for high frequencies, effectively reducing the temperature rise of PFC and output inductor.

No noise interference

Near-zero magnetostriction is suitable for silent equipment.

Application Scenario Analysis

Photovoltaic/energy storage PFC inductor

In grid-connected inverters and energy storage DC/DC converters, magnetic powder cores serve as the core of PFC inductors, balancing losses and energy storage at high switching frequencies.

Technical Value:
  • Extremely high cost-performance ratio, maintaining high inductance under high current;
  • Core losses far lower than iron powder cores, reducing thermal design stress;
  • Good temperature stability, suitable for harsh outdoor environments.
New energy vehicles OBC and DC/DC

On-board chargers have extremely small size requirements, and the high-throughput series offers the highest energy efficiency ratio and power density.

Technical Value:
  • With a Bs value as high as 1.5T, it can carry large currents in extremely small spaces.
  • Its DC bias resistance is industry-leading, preventing transient current saturation.
  • It meets automotive-grade vibration and shock reliability requirements.
High-precision UPS and aviation power supplies

It is used in filters and inductors where efficiency and accuracy are extremely important, providing the lowest loss and the highest stability.

Technical Value:
  • Lowest loss among all powder cores, with efficiency approaching that of ferrite cores.
  • Excellent temperature coefficient ensures constant parameters under complex loads.
  • Superior performance in suppressing common-mode and differential-mode interference.
High-power industrial charging module

For high-power modules ranging from 15kW to 60kW, the iron-silicon series exhibits extremely robust anti-saturation resistance under ultra-high current conditions.

Technical Value:
  • High DC bias capability is more than 30% better than iron-silicon-aluminum composites.
  • Suitable for low-to-medium frequency, ultra-high current output filtering.
  • Significant cost advantage, facilitating large-scale industrial deployment.
