Abstract:
Single and polyphase a. c. induction devices, such as: motors, generators, transformers, welders, ballasts, etc. are so wound as to maximize performance and efficiency. For each phase of such device this invention utilizes a combined pair of windings which are conductively and inductively dependent. An energy supply winding of each combined pair is electrically connected to a corresponding input/output phase, while the remaining, or reflux, winding of each pair is electrically connected in series with a tunable capacitive element and to neutral or electrical ground by means of a linear and non-linear resistive means. The energy and reflux windings of each combined pair are positioned within the device in tight-to-critically coupled transformer relationship with a third inductive input/output component and the capacitive reactance adjusted to reduce to a minimum the net reactive factor of the coupled inductive elements and the net reflected impedance of the input/output circuitry, thus facilitating maximum energy transfer and efficiency.
