Higher power throughput
Nanocrystalline metals Cores are ideally suited for diverse range of applications such as:-
Frequency of operation is from 50 Hz to MHz range
Common Applications are
Switch Mode Power Supply
Common Mode Choke
Uninterruptible power systems
Pulsed welding equipment
Power inverter (e.g. solar inverter)
Nanocrystalline material has the potential as lower cost alternatives to the costly Cobalt-based Amorphous material in many applications. This is due to the excellent soft magnetic properties.
Extremely Low Coercivity
Low Energy Losses
High Saturation Flux Density
Mag amps are particularly well suited for outputs with currents of 1 amp to several tens of amps, although they are also used at lower currents where tight regulation and efficiency are extremely important.
Conventional regulated outputs are limited at higher frequencies and output currents. Linear regulators cannot handle output currents that exceed one or two amperes efficiently, and thus require heat sinking schemes, which increase the size of the power supply. Independent switched-mode sub-regulators avoid this inefficiency, but usually require circuitry which is more complex, expensive and less reliable than a mag amp.
Standard sizes are available from 9.6 mm to 34.1 mm OD and the possibility of manufacturing custom sizes also exists. Core coatings meeting UL94V-0 and temperature class F are available upon request.
Square Loop magnetic cores are specifically designed to exhibit an extremely square dc hysteresis loop and high Bsat resulting in the following important benefits:
Low Saturated Permeability
Low Coercive Field – including a small reset current
Low Profile – enabling weight and volume reduction of up to 50%
Low Loss – resulting from micro-thin cobalt based amorphous ribbon (18um)
IRON BASED AMORPHOUS magnetic toroidal choke cores are ideally suited for a diverse range of applications such as:
DC output inductors
Power factor correction chokes
Differential mode input chokes
IRON BASED AMORPHOUS magnetic toroidal choke cores are specifically designed to exhibit a dc hyteresis loop resulting in the following important benefits:
Linear Permeability – over a wide range of magnetizing force
High Saturation Flux Density (1.56 T)
Significant Size Reduction – due to high saturation induction
Low Temperature Rise – due to low losses
Low loss – resulting from micro-thin IRON BASED AMORPHOUS ribbon (22um)
Output Filter or Inductor cores in High Frequency & High Power (generally >50KW),
Solar, Hybrid Automobiles, Railway Powers and wind inverter.
High Saturating Flux Density (Reducing volume and weight of the core)
Low ore loss —Lower temperature rising, higher efficiency of the transformer
Excellent temperature stability —Keep stale working at -5’C-3’C for log tie
