Karolo ea mantlha ke ho matlafatsa matla a khoheli a pakeng tsa likhoele tse peli. Bakeng sa ho fokotsa tahlehelo ea "eddy" hajoale le "hysteresis" ka tšepe, mokokotlo oa tšepe o theoa ka ho hlakola maqephe a tšepe a silika; ha ho na khokahano ea motlakase lipakeng tsa makhetlo a mabeli, 'me likhoele li lematsoa ke likhoele tsa koporo tse koahetsoeng (kapa lithapo tsa aluminium). Kela e le 'ngoe e hoketsoeng ho matla a AC e bitsoa coil ea mantlha (kapa coil ea mantlha),' me kela e 'ngoe e hokahantsoeng le sesebelisoa sa motlakase e bitsoa coil ea bobeli (kapa coil ea bobeli). Transformer ea 'nete e thata haholo. Ho na le tahlehelo e ke keng ea qojoa ea koporo (ho futhumatsa ha coil resistance), tahlehelo ea tšepe (ho futhumatsa ha mantlha), le ho dutla ha matla a khoheli (terata e koalang moea o khoheli). Ho nolofatsa puisano, ke transformer e loketseng feela e hlahisoang mona. Maemo a hore phetoho e ntle e lokelang ho theoa ke: iphapanye le phallo ea matla a khoheli, o hlokomolohe khanyetso ea li-coil tsa mantlha le tsa bobeli, u hlokomolohe tahlehelo ea mantlha, 'me u hlokomolohe ha hona mojaro oa hajoale (hajoale o le khoeleng ea mantlha ha kela ea bobeli e butsoe). Mohlala, ha sesebelisoa sa motlakase se sebetsa ka bongata (matla a tlhahiso ea coil ea bobeli) e haufi le boemo bo nepahetseng ba phetoho.

Li-transformer ke lisebelisoa tsa motlakase tse sa sebetseng tse entsoeng ka molao-motheo oa induction ea motlakase. Ha coil e ka sehloohong ea transformer e hokahane le mohloli oa matla a AC, ho hlahisoa phallo ea makenete e fapanyetsanang bohareng, 'me matla a khoheli a fapanyetsanang hangata a hlahisoa ke φ.

Ho ea ka molao oa Faraday oa ho kenngoa ha motlakase oa motlakase, matla a motlakase a bakoang ke li-coil tsa mathomo le tsa bobeli ke e1 = -N1dφ / dt le e2 = -N2dφ / dt. Ka foromo, N1 le N2 ke palo ea ho fetoha ha li-coil tsa mantlha le tsa bobeli. E ka bonoa ho tsoa setšoantšong hore U1 = -e1 le U2 = e2 (palo ea 'mele ea coil ea pele e emeloa ke subscript 1 le palo ea' mele ea coil ea bobeli e emeloa ke subscript 2). Mekhoa e sebetsang e rarahaneng ke U1 = -E1 = jN1ωΦ, U2 = E2 = -jN2ωΦ, Let k = N1 / N2, e bitsoang karolelano ea transformer. Ho ea ka mokhoa o boletsoeng ka holimo, U1 / U2 = -N1 / N2 = -k, ke hore, karo-karolelano ea boleng bo sebetsang ba motlakase oa motlakase oa motlakase oa motlakase oa motlakase oa motlakase le oa bobeli o lekana le karo-karolelano ea ho fetoha le phapang pakeng tsa karolo ea mantlha le ea bobeli. matla a khoele ke π.
