Abstract :
This paper solves problematic of supply voltage dips and their influence to modern electric drive (i.e. induction machine supplied from indirect frequency converter). The paper presents the control algorithms for basic variant the most used drives (with non-controlled rectifier and without additional converter) and variants with more complicated power circuits (with active rectifier respectively with special additional step-up boost converter in DC-link).
