Since the development of renewable energy like solar, wind power, the multi-level topologies proved to be more able to apply and control the renewable energy systems. Although, the multi-level inverter generate a common-mode voltage less than the two-level inverter. The common-mode voltage problem still researchers study and solve. This paper will be presented a simple and flexible technique to reduce...
In electric drive applications, the conventional carrier based and space vector pulse width modulation (PWM) which schemes for two-level inverter topology generate large common-mode voltages, this leads to the phenomenon of bearing current. These current spikes can cause electromagnetic interference (EMI) and reduction in the life expectancy of the motor. Cascade multilevel inverters can reduce voltage...
