Amorphous Choke Cores PFC Output

Amorphous Choke Cores for High-Efficiency PFC Output Applications

FERRTX Amorphous Choke Cores are engineered specifically for modern PFC output stages, where low loss, high impedance stability, and compact component size are essential. Compared with traditional ferrite structures, our Amorphous Core Choke solutions deliver superior saturation characteristics and reduced temperature rise, enabling higher power density and higher conversion efficiency in today’s power supplies.

Built from premium Amorphous Magnetic Materials, these cores support excellent common-mode and differential-mode performance, making them ideal for next-generation PFC systems, server power units, EV chargers, and industrial power converters.

Why Choose an Amorphous Core Choke?

High Saturation & Stable Inductance

The unique amorphous microstructure maintains stable AL values under heavy current load, ensuring consistent performance in toroidal choke PFC output circuits.

Low Core Loss at High Frequencies

Amorphous metals minimize eddy-current loss, enabling cooler operation and higher efficiency—especially valuable for High Frequency Transformer power architectures.

Smaller Size for High-Power Designs

Compared with conventional ferrite parts, Amorphous Choke Cores can achieve equivalent impedance with reduced dimensions, supporting the trend toward compact power supply design.

Wide Frequency Compatibility

Ideal for high-frequency PFC control loops and variable-speed power conversion systems.

Typical Applications

Our Amorphous Common Mode Choke and differential-mode PFC chokes are widely used in:

• PFC Output inductors for AC-DC server and telecom power

• High-efficiency Power Converter and DC-DC systems

• EV charging modules and industrial automation equipment

• UPS and energy-storage inverters

• Noise-suppression and EMI reduction circuits

• Power stages requiring stable high-impedance chokes

The high permeability and strong DC-bias capability make these cores reliable for both high-current and high-frequency choke configurations.
