ABSTRACT:
An improved circuit and device uses a dual primary winding transformer, where the primary windings are connected in series, and where each winding has a center tapped ground. A series of four switches are attached to the ends of the two primary windings to sequentially feed the primary windings. The switches are controlled by a pair of oscillators, the first two switches on one primary winding controlled by a first oscillator, and the second two switches of the other primary winding controlled by a second oscillator. Both the first and second oscillator are controlled by a phase displacement controller which can vary the relative timing of the two oscillators to control the transformer output. A zero phase angle delivers maximum power, while a 180.degree. phase displacement delivers zero power, enabling precise control across the zero to full power spectrum. A series of feedback controls measure the current and voltage of the output of a rectifier bridge to even more closely control the power output. A dual inverter utilizes a single transformer for light weight, efficient operation.
