PLF-Low Core Loss Iron Silicon Core Series

Low Core Loss Iron-Silicon Cores for High-Efficiency Transformers and Reactors

POURLEROI's low core loss iron-silicon cores are designed to meet the efficiency and reliability demands of industrial transformers, power inductors, and magnetic reactors. Featuring high permeability and excellent frequency response, these cores minimize hysteresis and eddy current loss in power conversion applications.

What Are Low Core Loss Iron-Silicon Cores?

Iron-silicon cores, also known as silicon steel cores, are made by alloying electrical-grade iron with a controlled percentage of silicon (typically 1.0–3.5%). The addition of silicon reduces hysteresis loss and electrical conductivity, improving both magnetic and thermal performance. POURLEROI’s low-loss silicon steel cores are manufactured with precision lamination or strip-wound techniques, ideal for high-efficiency, medium-frequency magnetic circuits in industrial and grid applications.

Product Overview

Our low-loss Fe-Si cores are produced using high-grade silicon steel sheets with high magnetic flux density, low coercivity, and minimized eddy current loss through grain orientation and thin lamination. We offer both cold-rolled grain-oriented (CRGO) and non-oriented (CRNGO) materials depending on your frequency and core size requirements.
These cores are commonly used in line-frequency transformers, power reactors, output inductors, and magnetic amplifiers that demand low power loss and high stability under continuous operation. Our manufacturing processes ensure uniform stacking factors, tight dimensional tolerances, and insulation coatings that meet industry standards for thermal class and dielectric strength.
POURLEROI supports custom cut cores, C-cores, and EI laminations for specific industrial use cases, including dry-type transformers, solar inverters, and power distribution systems.
