Abstract – Space Vector Modulation (SVM) is widely used in industrial drives applications, and due its flexibility for the selection of the switching sequences as well as its suitability for digital implementation it is rapidly gaining favour in other applications such uninterruptible power supplies, force commutated rectifiers and active filters. In this context, this paper presents simple filter design procedure for different voltage fed space vector modulated (SVM) converters. The proposed design procedure is applied to six basic converters including single-phase and three-phase voltage fed rectifiers and inverters. Although, the normalized curves used in the design have been derived for a given symmetric switching sequence, it can be easily extended to other switching sequences. The paper describes in detail the proposed filter design procedure, including the supporting hypothesis and simplifications as well as a brief description of the SVM for converters considered. Aiming demonstrate the validity of the proposed design procedure, experimental results are also included.
