Abstract
This paper presents the analysis of the dc-link voltage switch-ing ripple in five-phase PWM voltage source inverters with balanced load. The analysis is particularly important for the design and selection of a dc-link capacitor making it possible to meet desired electrical performance of the inverter system. Simple and practical equation for designing the dc-link capac-itor is proposed relating the value of capacitance to the max-imum value (peak-to-peak) of the dc-link voltage ripple. The amplitude of the dc-link voltage switching ripple is analyti-cally derived as a function of modulation index, and the am-plitude of the output current and phase angle. In order to show peak-to-peak voltage ripple distribution different dia-grams are introduced. Reference is made to continuous sym-metric centered PWM modulation (i.e., space vector modula-tion SVM). In order to verify proposed developments, simula-tions have been carried out by Matlab/Simulnik considering full range of modulation index and output phase angle.
