2 General Defntns. BH curves If an alternatng magnetc feld s appled t a sft magnetc materal, the magnetc nductn(b) changes wth the magnetc feld(h)as shwn n Fg. The hysteress lp, descrbng the relatn between H and B, s called the magnetzatn curve. BH LOOP B B s B r I H H c Fg.. Intal permeablty B H where : permeablty f vacuum The ntal permeablty defnes the relatve permeablty at lw exctatn level. Accrdng t IEC 64 test cndtn : f< KHz, B <.5mT, 5. Saturatn magnetzatn, B s At hgh feld strength, the nductn flattens ut at a value, called the saturatn flux densty, B. S.

3 General Defntns. Permeablty Permeablty s defned as the rat f flux densty t the magnetc feld stength. Ths parameter can be measured under the dfferent sets f cndtns.. Intal permeablty The ntal permeablty s defned as the relatve permeablty at lw exctatn level and cnsttutes the mst mprtant means fr the cmparsn f sft magnetc materals.. Effectve permeablty If an ar gap s ntrduced n a clsed magnetc crcut, magnetc nductn becmes mre dffcult. As a result, the flux densty fr a gven magnetc feld strength becmes lwer. Effectve permeablty depends n the ntal permeablty f the sft magnetc materal, the sze f ar gap and the cre shape. The effectve permeablty s determned by the frmula belw, e L N l A where l A : cre factr L : effectve nductance(ar gap). Cmplex permeablty T enable a better cmparsn f ferrte materals and ther frequency characterstcs at a very lw feld strength t s useful t ntrduce as a cmplex peratr. = s' j s'' where ' : real part f the seres cmplex permeablty s s'': magnary part f the seres cmplex permeablty 4 Fg. 4 8

At relatvely lw nductn, a ncreases wth H but as the magnetzatn reaches saturatn, a decreases wth H. Such a curve s shwn n Fg Fg. Magnetc cre shape characterstcs.

Pwer lss Fr hgh exctatn applcatn, such as pwer transfrmer desgn n Swtchng Mde Pwer Supples (SMPS), the energy dsspatn(lsses) s expressed n terms f pwer lss. Pwer lsses are functn nt nly f ferrte materal but als nductn level(b), peratng frequency(f) and temperature(t). Pwer lss can be dvded nt three cmpnents. P L = P + P + P Hysteress Eddy current Resdual 6. Other characterstcs 6. Ttal harmnc dstrtn, THD In mdern telecmmuncatn applcatns lke ISDN and DSL, ferrtecred pulse and wdeband transfrmers play an mprtant rle. These transfrmers prvde mpedance matchng and safe slatn n mdems placed between netwrks and telephnes set r cmputers. Ttal harmnc dstrtn, THD, s defned as the frmula belw. Ths factr ndcates the degree f sgnal wave dstrtn fr the telecmmuncatn applcatn. The THD f ferrte cmpnent shuld be lw under peratng cndtns. THD s a functn f flux densty (B), frequency (f) and temperatures (T). T evaluate materal qualty wth respect t THD, V and V shuld be measured wth aud analyzer ( tested by ATS equpment) THD = lg V V / a where V = ampltude f frst harmnc wave V = ampltude f thrd harmnc wave THD ncreases when the flux densty level rses. At frst THD can be explaned by the fact that pres and mpurtes nsde the materal act as pnnng pnts fr the dman wall mvement such an rreversble jump makes an dstrtn. Secnd THD s a functn f bth the ntrnsc prpertes f ferrte materal such as permeablty and hysteress lss ceffcent, and extrnsc prpertes such as the cndtn f matchng surfaces. Bad planarty r grndng grves wll cause magnetc flux cncentratns, whch ncrease the dstrtn level, especally when the surfaces are drectly n cntact wth each thers. 6. Cure temperature, T C Cure temperature s the pnt at whch ferrte lse there ferrmagnetc character, due t thermal vbratn.

Densty, d The densty s defned as the weght per unt vlume. d= w v where W : weght f the magnetc cre (g) V : vlume f the magnetc cre (cm ) 6.4 Electrcal resstvty, The resstvty s defned by the frmula belw, = A R P Where A : area f current path : length f current path R P : parallel resstance Ferrte s a semcnductr wth a DC resstvty n the crystalltes f the rder f m fr a MnZn ferrte. Snce there s an slatn layer between the crystals, the bulk resstvty s much hgher:. m t m fr MnZn ferrte Ths resstvty depends n the temperature and measurng frequency. 6.5 Dsaccmmdatn, DF When a sft magnetc materal s gven a magnetc r thermal dsturbance, the permeablty rses suddenly. The dsacmmdatn factr makes t pssble t estmates the change f permeablty fr a lng tme. IEC has defned a dsacmmdatn ceffcent as fllws, DF = (lgt ) lgt Where : permeablty at tme t : permeablty at tme t and t t 6.6 Relatve Temperature ceffcent, F The permeablty f ferrte s a functn f temperature. It generally ncrease wth temperature t maxmum value and then drps sharply t lse ther ferrmagnetc prpertes. Temperature ceffcent f a ferrte cre wth argap decrease at the same rate as des the ntal permeablty. F = T T Where : ntal permeablty at T =5 C : ntal permeablty asscated wth the temperature T
