PURPOSE:To obtain a superconductive transformer having about one half of the area as compared with the conventional one, the inductance and transforma tion ratio being unchanged, by arranging primary side superconductive films on both-upper and lower-sides of the secondary side superconductive films. CONSTITUTION:The primary side current enters a primary side input terminal 17, thus two times around the upper side of two secondary side superconductive films 140, 141, flows through ground plane hole 18, enters the lower side of the ground plane, turns two times around the lower side of the films 140, 141, and finally reaches the ground plane. As there exist two films 140, 141 as superconductive film 14, the output is obtainable from either of the secondary output terminals the other ends of which are grounded. An identical current flows in the sequence of 1-4 in the four primary coils wound on the upper side of the secondary coils 140, 141. Similarly, in the four primary coils wound on the lower side, the current flowing from 4 through the ground plane hole 18 flows in the sequence of 5-8, and finally into the ground from 8. Thus the same transformation ratio is obtainable with half the width and with the same inductance as before. |
