A Simplified and Generalized SVPWM Scheme for Two-Level Multiphase Inverters With Common-Mode Voltage Reduction

IEEE transactions on industrial electronics (1982. Print), 2021
Multiphase space vector pulsewidth modulation (SVPWM) method has gained much attention with the growing interest in multiphase motor drives. Conventional multiphase SVPWM becomes more complex with the increase of phases, while simplified multiphase SVPWM

An approach to reduce common-mode voltage in matrix converter

IEEE Transactions on Industry Applications, 2003
In this paper, an approach to reduce common-mode voltage at the output of a matrix converter is discussed. A new modulation strategy which reduces the common-mode voltage at the output is presented. The proposed method maintains the active voltage vector and distributes zero vector equally within a sampling period and reduces square RMS of ripple ...
