Common-Mode Voltage Reduction in VSI-Fed Motor Drives With an Integrated Active Zero-State Switch

IEEE Journal of Emerging and Selected Topics in Power Electronics, 2022
Common-mode voltage (CMV) produced by voltage source inverters (VSI) is of great concern in motor drive systems. A significant amount of conducted common-mode/bearing current will be induced and will interfere with system operation.
