Transient overvoltages at motor terminals and highfrequency common-mode currents in PWM drive systems have been extensively investigated in the last fifteen years. Nevertheless, some issues concerning such quantities still remain unclear. That is the case of the converter-to-motor cabling influence on the intensity of these high-frequency voltages and currents. Filters of different types have been traditionally used to mitigate these undesired phenomena. However, due to their cost, volume and losses, they can't be considered the ultimate solution of the problem. In this paper, typical industrial cable arrangements will be characterized in terms of the generated transient overvoltages and common-mode currents. It will be shown that variations in the range of 10 to 40 % in the peak values of these quantitites can take place due to different cable disposition. Thus, it can be concluded that special care in the cable installation can lead to significant reduction in these undesired phenom-ena, which in turn downsizes the required filter.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
