Improve efficiently soft-starter transients' immunity
Silicon controlled rectifiers (SCR) or reduced voltage soft-starters (RVSS) smooth motor starting in MV power systems. Most literature on SCR design discusses motor or system protection, but little is said about protection of SCR itself.
This paper presents a mathematical analysis on MV SCRs for the purpose of protecting the power electronics components while turning on. The role of current transient in damaging soft-starters is discussed, and a simple tool for practical SCR transient protection design is described.
