Abstract: A device and method of use for a phase shifting autotransformer is disclosed which has inherently balanced impedance characteristics. This is achieved by having the coil windings structured such that the following two requirements are met. Equivalent winding sections must have essentially equal lengths, occupy equal radial volumes and therefore exhibit equal resistances. Secondly, semi-bifilar or full-bifilar construction ensures that the inductances generated in each section essentially cancel each other out, minimizing the reactive component of the impedance such that it can be dominated by the resistive component in operation. As a result of these two design elements, the 5th and 7th harmonics that dominate 6-pulse systems can be attenuated much more effectively than was previously possible, improving both the overall performance of the phase shifting autotransformer itself, as well as its associate system.

Abstract: Data may be encoded onto a direct current power line by modulating the current on that direct current power line. One method of modulating the current is by placing an inductor on the power line and then using a controlled transistor that turns on and turns off. The inductor will ensure that current keeps flowing but the transistor will induce changes in the current pattern. The excess current from when transistor is turned off must be diverted. Furthermore, to create symmetrical current changes, the inductor should be reverse biased. Thus, a circuit is created that sinks the excess current from when the transistor is turned off and used to reverse bias the inductor.
