1. B-H curves

If an alternating magnetic field is applied to a soft magnetic material, the magnetic induction(B) changes with the

magnetic field(H)as shown in Fig. 1

The hysteresis loop, describing the relation between H and B, is called the magnetization curve.

2. PermeabilityPermeability is defined as the ratio of flux density to the magnetic field stength.

This parameter can be measured under the different sets of conditions.

2.1 Initial permeability The initial permeability � is defined as the relative permeability at low excitation level and constitutes the most i

important means for the comparison of soft magnetic materials.

2.2 Effective permeabilityIf an air gap is introduced in a closed magnetic circuit, magnetic induction becomes more difficult.As a result, the flux density for a given magnetic field strength becomes lower.Effective permeability depends on the initial permeability of the soft magnetic material, the size of air gap and the core shape.The effective permeability is determined by the formula below,�

5. Loss expressions in the high excitation range

5.1 Power lossFor high excitation application, such as power transformer design in Switching Mode Power Supplies (SMPS), the energy dissipation(losses) is expressed in terms of power loss. Power losses are function not only of ferrite material but alsoinduction level(B), operating frequency(F) and temperature(T).Power loss can be divided into three components.

6. Other characteristics

6.1 Total harmonic distortion, THDIn modern telecommunication applications like ISDN and DSL, ferrite-cored pulse and wideband transformers play an important role.These transformers provide impedance matching and safe isolation in modems placed between networks and telephones set or computers.Total harmonic distortion, THD, is defined as the formula below.This factor indicates the degree of signal wave distortion for the telecommunication application.The THD of ferrite component should be low under operating conditions.

THD is a function of flux density (B), frequency (f) and temperatures (T).To evaluate material quality with respect to THD , V1 and V3 should be measured with audio analyzer ( tested by ATS-1 equipment)

a

V

V �/log203

1 ��THD =

where V = amplitude of first harmonic wave1

V = amplitude of third harmonic wave3

THD increases when the flux density level rises.

THD can be explained by the fact that pores and impurities inside the material act as pinning points for the domain wall movement such an irreversible jump makes an distortion.

SecondTHD is a function of both the intrinsic properties of ferrite material such as permeability and hysteresis loss coefficient, and extrinsic properties such as the condition of matching surfaces.Bad planarity or grinding grooves will cause magnetic flux concentrations, which increase the distortion level, especially when the surfaces are directly in contact with each others.

6.2 Curie temperature, TC

6.3 Density, dThe density is defined as the weight per unit volume.

where W : weight of the magnetic core (g)3 V : volume of the magnetic core (cm )

6.4 Electrical resistivity,The resistivity is defined by the formula below,

Where A : area of current path : length of current path

-3Ferrite is a semiconductor with a DC resistivity in the crystallites of the order of 10 � m for a MnZn ferrite.Since there is an isolation layer between the crystals, the bulk resistivity is much higher: 0.1� m to 10� m for MnZn ferriteThis resistivity depends on the temperature and measuring frequency.

6.5 Disaccommodation, DFWhen a soft magnetic material is given a magnetic or thermal disturbance, the permeability rises suddenly.The disacommodation factor makes it possible to estimates the change of permeability for a long time.IEC has defined a disacommodation coefficient as follows,

6.6 Relative Temperature coefficient, � F

The permeability of ferrite is a function of temperature.It generally increase with temperature to maximum value and then drops sharply to lose their ferromagnetic properties.Temperature coefficient of a ferrite core with air-gap decrease at the same rate as does the initial permeability.
