H8 Inverter for Common-Mode Voltage Reduction in Electric Drives [PDF]
IEEE Transactions on Industry Applications, 2016 This paper presents a modified two-level three-phase inverter for the reduction of the leakage current. With respect to a traditional two-level inverter, the proposed solution reduces the common-mode voltage (CMV), both in amplitude and frequency. Between the dc source and the traditional three-phase bridge, two active dc-decoupling devices and a ...
