Power Semiconductor Switches for Pulse Power Transformers with a Modular and Scalable Architecture

This article discusses unconventional circuit solutions for construction of reversible multifunctional pulse converters (MPCs) of ac—including three-phase—and dc voltages with adjustable parameters, correction of the power factor, a specified shape of external volt–ampere characteristics, and soft swiching. Such reversible MPCs presuppose a flexible modular and scalable architecture with serial and parallel increase in the number of modules. The proposed solutions allow for synthesis of transportation and stationary power generation systems with a high-tech flexible modular and scalable architecture using domestic items of power semiconductor switches. The article may be useful for a wide circle of researchers and developers of secondary power-supply sources for stationary and transport power-supply systems, in particular, those for promising fully electric aircraft, transport traction electric power transmission systems with overhead-contact and self-contained power supply that provides for the return of energy to the source under regenerative braking, wind and diesel power plants, “high-voltage electronic transformers,” etc.
