PART IIL Two of the commonest types of transformers used in audio frequency circuits are shown in Figs. 1 and The type shown in Fig. 1 is known as a ‘“‘core-type” transformer, while the one shown in Flg. 2 is known as a “shell-type” transformer. In the core-type transformer the primary and secondary ‘windings are both wound around one leg of the transformer core, making the ratio of average length of electrical circuit to magnetic circuit small as compared to the ratio of electrical circuit to mag- circut in the shelltype trans- former. Proximity Causes Howls. Due to the high value of the exter- nal magnetic fleld of the core-type transformer, the amount of howling which it produces because of proxim- ity of transformers and wiring is much greater than that which s ob- tained when the shell type of trans- former is used. In a new transformer the designers have gone a step farther in reducing the external fleld by inclosing the coll almost completel e core of the new transformer shown in Fig. 8 is of the shell type shown in Fig. 2 Fig-3 except that two other legs of the core extend at right angles to the external core sections shown in Fig. The fron core in an audio frequency transformer is used to confine the magnetic fleld as much as possible close to the coils themselves by of- fering a path of minimum reluctance or opposition to the flow of the mag- netic flux. The main losses in a transformer occur in the fron core so that the design of this element of the device is a very important factor in de- termining its efficiency. Losses in Transformer. The most important losses in a transformer are due to hysteresis and eddy currents and are the result of The hystere- «is loss is due to the fact that the changing direction of current flow in the primary or the variation in cur rent strength in the primary in the case of a pulsating current require the use of some energy to effect the change in strength or reversal of polarity of the magnetic condition of the iron. In- ferfor metal also causes the magnetic fleld to lag behind the current that produces the fleld. The eddy current losses are the re- | sult of the formation of electrical currents in the material of which the core is made and the way in which the core is censtructed. Magnetic Loss. Another loss that occurs in a trans- former is that of magnetic leakage, due to the fact that all of the lines of flux produced by the primary wind- effective in cutting the secondary Windings. It _would seem that the elimination of the iron would do away with hys- COUGH IS YOUR ~ DANGER SIGNAL Persistent coughs and colds lead to serious trouble.
