Modular converters based on the connection of multiple power cells have become a competitive solution for many applications achieving high performance with reduced production and maintenance cost. However, their performance is degraded if the power modules present an unbalanced operation which is a common case in some applications and/or when...

Electric variable speed drives (VSD) have been replacing mechanic and hydraulic systems in many sectors of industry and transportation because of their better performance and reduced cost. However, the electric systems still face the issue of being considered less reliable than the mechanical ones. For this reason, researchers have been...

Electric variable speed drives (VSDs) based on two VSDs connected to a multiphase machine are an attractive solution to replace high-power mechanic and hydraulic systems in many sectors of industry and transportation because they present high performance with reduced cost, volume and weight. Among the causes which affect the reliability of dual...

Common-mode voltage (CMV) in electric drives causes leakage current causing consequently EMI problems, loss and reduction of their components' lifetime. Several solutions have been proposed which usually lead to higher cost because additional components are used. This paper is focused on the mitigation of the resulting CMV produced by the...
