Application Scenario Analysis
Megawatt-class photovoltaic inverters
In large centralized inverters, the nanocrystalline ring serves as the core of the output EMC filter, responsible for suppressing high-frequency harmonics.
Technical Value:
- Significantly reduces grid-connected current distortion (THDi);
- Excellent DC bias tolerance, handling large current fluctuations；
- High-efficiency conversion, reducing power plant operating losses.
EV Supercharger (480kW+)
Inside the ultra-fast charging module, the magnetic core directly carries hundreds of amperes of current, requiring extremely high magnetic saturation characteristics.
Technical Value:
- The volume is reduced by more than 35% compared to traditional magnetic powder cores.
- It solves the persistent heat dissipation problem caused by high power density.
- It ensures electromagnetic compatibility (EMC) during charging meets automotive-grade standards.
Rail transit traction system
It is used in high-speed rail and subway converters, facing extremely harsh mechanical vibration and temperature difference challenges.
Technical Value:
- Nanocrystalline materials exhibit no magnetic attenuation at high temperatures;
- Lightweight design effectively reduces the unsprung weight of the bogie;
- High reliability ensures long-term trouble-free operation of the locomotive.
Large industrial high voltage frequency converter
The high-frequency bearing current caused by PWM modulation is absorbed by the large toroidal core wrapped around the motor cable.
Technical Value:
- Prevents failure caused by electro-corrosion of motor bearings.
- Extremely high impedance performance provides the strongest suppression effect.
- Easy installation, no internal modification of the motor required.
Offshore wind power converter
For the high humidity and high salt spray environment at sea, we provide large-size nanocrystalline magnetic cores with a fully enclosed structure.
Technical Value:
- Provides linear and smooth magnetic permeability to cope with unstable wind energy input.
- Hermetically sealed design ensures a lifespan of over 20 years.
- Single-cell size supports OD 500mm, meeting megawatt-level grid connection requirements.
