In the case of a five-phase inverter supplying a five-phase R – L load, the dc-link voltage ripple across the dc-link capacitor was measured by Tektronix P5205A, 100 MHz, high voltage differential probe.
In general, a large dc-link capacitor can significantly reduce the voltage ripple, and smooth dc-link voltage can be obtained. As a consequence, the dc-link capacitors are often oversized. Such heavy and bulky capacitors can become a critical obstacle to the high power density of the inverter system.
Author to whom correspondence should be addressed. Direct current (DC)-link voltage ripple analysis is essential for determining harmonic noise and for DC-link capacitor design and selection in single-phase pulse-width modulation (PWM) inverters.
The dc-link voltage ripple amplitude is calculated in Refs. [23, 24], and the dc-link capacitor design is proposed based on the dc-link voltage switching ripple requirements for five- and seven-phase inverters, respectively. The impact of the number of phases on input current ripple has been analysed in Ref. .
Abstract — Determination of current ripple in three-phase PWM voltage source inverters (VSI) is important for both de-sign and control purposes, since this is the most popular conver-sion topology for energy conversion systems.
