New mathematical model for analysing three-phase controlled rectifier using switching functions

This paper proposes a fast, accurate, and effective steady state mathematical model for analysing 3-phase full-wave controlled rectifiers. The proposed mathematical model, unlike conventional analytical methods, can be integrated in the design of active power filters. It enables the assessment of the problem of injecting voltage and current harmonics into the power system and it determines the modulating signal for the active filters. This paper shows, for the first time, that the switching function technique can be applied into the control of any type of voltage fed converters.
