N2 - Common-mode voltage (CMV) is an inherent issue in motor drive systems, primarily caused by instantaneous unbalanced voltage signals generated by the switching states of the inverter. The adverse effects of CMV are widely acknowledged as a critical concern, particularly in applications requiring stringent reliability standards. These effects become more pronounced with the increasing adoption of wide-bandgap semiconductors, which enable higher switching frequencies. Various methods have been proposed to mitigate CMV, encompassing both hardware and software solutions. However, these methods are often implemented independently, leading to a lack of collaborative integration. This paper investigates the synergistic effect of the inserted integrated CMV filter for PMSMs with sampling-time adaptive multi-carrier PWM. Both approaches have individually demonstrated effectiveness in reducing CMV, and their integration is expected to provide wellfounded guidance for parameter selection of the integrated filter, thereby fully leveraging the potential for enhanced whole system performance.
