Abstract
Abstract A transformer (T) with a primary winding (L1) and a secondary winding (L) coupled to the primary winding. A capacitive element (C) is coupled to the secondary winding for providing an increased output voltage level and an increased output current level from the transformer. The capacitive element may be either of distributed or lumped parameter structure. A reduction in the number of secondary winding turns may be compensated for with the capacitive element to maintain the same voltage output level as was obtained prior to reduction in secondary winding turns and also to obtain an increased current output level by virtue of the presence of the capacitive element and/or the reduction in the number of secondary winding turns. Such reduction in secondary winding turns reduces the physical size of the transformer as well as reducing its copper losses, and also reduces its cost of fabrication.
