A Novel Control Method for Transformerless H Bridge Cascaded STATCOM With Star Configuration

A Novel Control Method for Transformerless H-Bridge Cascaded STATCOM With Star Configuration: Abstract—This paper presents a transformerless static synchronous compensator (STATCOM) system based on multilevel H-bridge converter with star configuration. This proposed control methods devote themselves not only to the current loop control but also to the dc capacitor voltage regards to the current loop control, a nonlinear controller based on the passivity-based control (PBC) theory is used in thi
