Determination of dc-link voltage switching ripple in three-phase PWM voltage source inverters (VSI) is important for the selection and design of the dc-link capacitor. In this paper the complete analysis of the dc-link voltage ripple is given for three-phase PWM VSIs, in case of dc source impedance and balanced load. The dc voltage ripple amplitude is analytically determined as a function of amplitude and phase angle of output current, and modulation index. In particular, peak-to-peak distribution and maximum amplitude over the fundamental period of the dc voltage switching ripple are obtained. Guidelines for designing the dc-link capacitor are given on the basis of the dc-voltage ripple requirements. Simulations results carried out by Matlab/Simulink are provided to verify the analytical developments.

Abstract

Determination of dc-link voltage switching ripple in three-phase PWM voltage source inverters (VSI) is important for the selection and design of the dc-link capacitor. In this paper the complete analysis of the dc-link voltage ripple is given for three-phase PWM VSIs, in case of dc source impedance and balanced load. The dc voltage ripple amplitude is analytically determined as a function of amplitude and phase angle of output current, and modulation index. In particular, peak-to-peak distribution and maximum amplitude over the fundamental period of the dc voltage switching ripple are obtained. Guidelines for designing the dc-link capacitor are given on the basis of the dc-voltage ripple requirements. Simulations results carried out by Matlab/Simulink are provided to verify the analytical developments.
