Learn MoreNanocrystalline vs CRGO vs Ferrite Cores
Nanocrystalline cores offer superior performance characteristics compared to traditional CRGO (Cold Rolled Grain Oriented) silicon steel and ferrite cores, especially in high-frequency applications like EV chargers and current transformers. With typical flux density ranges of 1.2-1.3T compared to ferrite's 0.3-0.5T, nanocrystalline materials enable higher power density designs. Core losses are significantly lower at switching frequencies, with nanocrystalline showing 5-10x lower losses than ferrite at 100kHz. The superior magnetic properties result from the unique nanocrystalline structure that combines high permeability with excellent frequency response.

Frequently Asked Questions
What is a nanocrystalline transformer core?
A nanocrystalline transformer core is made from ultra-fine crystalline magnetic material with grain sizes of 10-20 nanometers. This unique structure provides superior magnetic properties including high permeability, low core losses, and excellent temperature stability, making them ideal for high-frequency applications like EV chargers and current transformers.
When to choose nanocrystalline vs ferrite cores?
Choose nanocrystalline cores when you need higher saturation flux density (1.2-1.3T vs 0.3-0.5T for ferrite), lower core losses at medium frequencies (1-100kHz), or better temperature stability. Ferrite cores are better for very high frequencies (>100kHz) and cost-sensitive applications. For EV chargers and precision CT applications, nanocrystalline offers superior performance.
What are the advantages of nanocrystalline cores in EV chargers?
Nanocrystalline cores in EV chargers provide 5-10x lower losses than ferrite at switching frequencies, enabling higher efficiency and power density. The higher saturation flux density allows for smaller transformer designs, while excellent thermal stability ensures reliable operation in demanding automotive environments.
How do nanocrystalline CT cores improve metering accuracy?
Nanocrystalline CT cores offer superior linearity, lower phase error, and higher permeability compared to traditional silicon steel cores. This results in better accuracy for revenue metering applications, especially at low current levels, and improved performance across wide frequency ranges.
