Method and apparatus for asymmetrically inducing voltages in transformer secondary windings while avoiding saturation of the transformer core

摘要

A method for magnetically inducing voltages in the secondary windings of a transformer without saturating its core. The method includes (a) applying to a first primary driven winding a first set of voltages, thereby generating (i) a first current in the first primary driven winding, (ii) a first magnetic field having a first quantum of energy, and (iii) a magnetically induced second set of voltages in the first secondary winding; (b) interrupting the first current, thereby causing the first magnetic field to collapse, and (c) not later than interrupting the first current, clamping the first primary driven winding to a third set of voltages, thereby magnetically inducing a fourth set of voltages in the first secondary winding. At least one of the fourth set of voltages is less than at least one of the second set of voltages. The method may further include the step of (d) applying to a second primary driven winding a fifth set of voltages having polarities opposite to polarities of the first set of voltages, thereby generating (i) a third current in the second primary driven winding (ii) a third magnetic field having a third quantum of energy, and (iii) a magnetically induced sixth set of voltages in the first secondary winding having polarities opposite to polarities of the second set of voltages.
