A Review of Reduction Methods of Impact of Common-Mode Voltage on Electric Drives

In this survey paper, typical solutions that focus on the reduction in negative effects resulting from common-mode voltage influence AC motor drive applications are re-examined. The critical effectiveness evaluation of considered methods is based experimental results tests performed a laboratory setup with an induction machine fed by inverter. capacity level and gradient du/dt limitation discussed to extend bearings’ lifetime increase windings’ safety. characteristic features described compared demonstrated using results.
