Abstract

Applications such as multiphase machine drives and wind energy conversion systems are normally based on voltage source converters (VSCs) which feature a convenient and familiar control scheme. In high-power medium voltage drives, three-phase current source converters (CSCs) are widely used owing to its simple topology, motor-friendly waveforms, power reversal capability, and short-circuit-inherited protection. Although controlling CSCs in three-phase is a troublesome, multi-phase CSCs gating generation and control are challenging. In this paper, a sinusoidal PWM-based controlled modulation index gating signal generator is introduced for five-phase CSCs. Two different simulation models have been built, using MATLAB/SIMULINK, to verify the proposed concept on rectification and inversion modes of the CSCs. The proposed controller provides a controllable linear modulation index with the availability of over modulation. © 2014 IEEE.
