Investigation of IGBT behavior in DC systems with advanced circuit breaker technology

Abstract

Certain advancements have been ongoing in power electronics, DC transmission is looking more advantageous than it ever has. Since the application of power converters and advanced circuit breaker technology, distribution, and transmission of DC energy has become increasingly dependable. Some of the motives for the tendency to select direct current circuit breakers (DCCB) for distributed power systems are clear, while some of the other reasons are not so apparent. The purpose of this paper is to communicate the findings of an investigation into basic IGBT switching behavior and the purpose for the choosing of these DC SSCBs for distributed power systems over the standard systems and devices already in place. Here, some General information about circuit breakers is provided. The two main types of circuit breakers for DC systems are discussed, though there are some other types that exist, we focus on these two types, electromechanical and solid state with preference given to the solid state. The advantages of Solid State circuit breakers are discussed. A mathematical model of IGBT has been conducted and discussed. The last thing outlined in the paper is a section about simulation results and analysis of the IGBT.
