A buck converter, boost converter, buck-boost converter, and other topologies utilize a pair (or more) of semiconductor devices that can be abstracted to a power pole primitive. This text explores a method to derive needed design and control models on a traditional power pole. These methods can then be applied to the proposed 5-terminal power pole. Compared to the traditional 4-terminal power pole, the proposed power pole offers greater control over waveform shapes. The potential benefits of the 5-terminal power pole become clear when analyzing the proposed topologies that utilize the 5-terminal building block. Primarily, this paper aims to provide the knowledge needed to construct (in simulation) and control a novel topology utilizing the 5-terminal power pole. This topology is in many ways similar to a buck converter, so buck converters are studied first in this paper. The analysis process applied to the buck converter is then applied to the proposed converter. By the end of the analysis, the reader should have the information to design these converters. Depending on the use case, the proposed converter has the potential to have reduced output ripple (voltage/current) compared to a buck converter with an equivalently sized passive filter. Therefore, if meeting an output ripple (noise) spec is a design goal, which it very often is, then the proposed topology has the potential to be smaller, in terms of physical footprint, and less expensive, in terms of money, than a buck converter. Finally, several other uses for the 5-terminal power pole are analyzed. The first use is a current splitter that can be used to make a single input, multiple-output switching power converter. Next, another novel topology is proposed that has two immediately obvious use cases. For one, it can be used to generate an oscillation (with potentially varying frequency or amplitude) while providing significant power, efficiently. Also, it can be used to generate an arbitrary waveform while providing significant power, efficiently.
