Product Introduction
TOROIDAL TAPE WOUND CORE FOR SWITCHING POWER TRANSFORMERS
To DC/AC and DC/DC converter used in EV, rail traffic, medical equipment and…, a core with high switching frequency, high power output, compact size and small weight, low loss and high energy efficiency are always demanded.
Basing on outstanding magnetic properties, such as: higher magnetic saturation flux density (1.23T), higher permeability (up to 200,000), better linearity and response of frequency to permeability and smaller low temperature dependence of permeability than normally ferrite (Mn-Zn), SWFNA nanocrystalline cores has become the first option for purpose of high-frequency power transformer.
Applications
High power high-frequency switching power transformer in telecommunication power supplies, UPSs, high-frequency heating power supplies, inverter welding machine power supplies and laser machine power supplies etc. instead of ferrite materials
Performance Features
High saturation magnetic flux density --three times to ferrite core and 2 times output power at the same size.
High permeability and low coercive
Low loss --Smaller excitation current enables low copper loss
Excellent stability
FEATURE
> High Frequency-80KHz
> High Saturation Flux Density
> Good Linearity & Response of Frequency to Permeability
BENEFIT
> High Transmittable Power
> Small Dimension & Weight
> High Energy Efficiency
Low Core Loss
HIGH-LIGHT
>> High Transmittable Power <<
>> Energy Efficiency to 99% <<
>>Smaller Dimension (1.5 times) than Ferrite<<
>>Wide Frequency Range-80KHz <<
CORE LOSS
In different magnetic flux density and different frequency (especially in high frequency range), SWFNA nanocrystalline core always has much lower loss than ferrite (Mn-Zn) core.
LINEARITY OF PERMEABILITY
In order to fill the specific technical requirements of power transformer core, magnetic properties nanocrystalline alloy could be adjusted by special annealing technique.
Figure 4. as a static hysteresis loop indicates that SWFNA power transformer core keeps very high linearity of permeability during the full current range.
