Impact of QSW‐ZVS on Input EMI Filter Design in DC‐DC Converters

open access: yesInternational Journal of Circuit Theory and Applications, EarlyView.
This paper analyzes the impact of quasi‐square wave zero voltage switching (QSW‐ZVS) on passive EMI filter design for DC‐DC buck converters. The extra element theorem (EET) is used to derive the design quantities that ensure converter performance is not altered, and the resulting damping element values are compared with those of traditional converters.

A Simplified Two‐Vector Approach for Common‐Mode Voltage Reduction in Model Predictive Control Drives of Permanent Magnet Synchronous Motor

open access: yesEnergy Science &Engineering, EarlyView.
In this study, a modified model predictive control scheme is proposed, in which a dedicated weighting factor is incorporated into the cost function to explicitly account for common‐mode voltage (CMV) effects during the control process. This modification leads to a significant reduction—up to 40%—in the magnitude of the generated CMV.
