Evaluation system for current source converter modulation techniques

Modulation techniques have been the subject of intensive research during last decades. They are used for generating switching patterns for several converter topologies. Nowadays, there are many proposals of modulation strategies applied to current source converters (CSC) and to voltage source converters (VSC). This paper presents an evaluation system for analyzing the characteristics, advantages and drawbacks of several modulation techniques used in CSC. This tool includes the study of carrier-based techniques and space-vector techniques. Implementation in rapid prototyping system Simulink/spl reg/-dSPACE/spl reg/ is described, simulation and experimental results obtained in 4 kVA current source converter are given. This evaluation system shows the operation, characteristics and properties of each modulation.
