    Abstract: A ferroresonant transformer having a mechanical adjustment in the limiting cross section of the core linking the secondary windings provided by a movable rectilinear segment in the leg on which the secondary is wound, with the longitudinal axes of movement of the segment being canted with respect to the axes of the leg so as to constitute an offset portion of the leg presenting a decreasing limiting cross section as the segment is withdrawn along its axis.

    Abstract translation: 一种铁磁共振变压器，其具有在芯的限制横截面中的机械调节，其连接由在其上缠绕有次级的腿部的腿部中的可移动直线段提供的次级绕组，该段的运动的纵向轴线相对于 从而构成腿部的偏移部分，当沿着其轴线取出片段时呈现减小的限制横截面。

    Abstract: FIG-01 A DC-TO-DC POWE CONVERTER INCORPORATING A COMBINED TRANSFORMER AND INDUCTOR DEVICE COMPRISES OF A THREE-LEGGED MAGNETIC STRUCTURE HAVING AN AIR GAP IN THE CENTER LEG AND PRIMARY AND SECONDARY WINDINGS ARRANGED ON THE THREE LEGS TO PROVIDE COMBINED COOPERATIVE TRANSFORMER AND INDUCTO/R ACTION. THE PRIMARY AND SECONDARY WINDINGS ARE EACH OF PUSH PULL CONFIGURATION, AND IN ONE FORM THE COOPERATING PRIMARY AND SECONDARY WINDING PUSH ARE POLED AND LOCATED TO PROVIDE MMF-BUCKING ACTION APLYING THE ENTIRE PRIMARY MMF ACROSS THE INDUCTOR LEG, WHILE IN ANOTHER FORM ONLY THE CORE MAGNETIZING MMF IS SEEN ACROSS THE INDUCTOR LEG, AND AN ADDITIONAL PROMARY WINDING IS PROVIDED TO BOOST THE FLUX IN THAT LEG. IN EACH CASE THE INDUCTOR LEG HAS AN AIR GAP TO PROVIDE IT WITH SIGNIFICANTLY HIGHER RELUCTANCE THAN THAT OF THE REMAINDER OF THE MAGNETIC CIRCUIT.
