This paper first outlines the benefits of medium voltage variable frequency drives compared to classical drivers or control methods (i.e. steam/gas turbines, hydraulic coupling and Direct-On-Line operation with, for example, valve/damper control). The paper then focuses on typical variable frequency drive applications in the sugar industry and also describes two real cases, namely an ABB drive ...
