The multilevel converter to achieve higher power is to use a series of power semiconductor switches with several lower voltage dc sources to perform the power conversion by synthesizing a staircase voltage waveform. Batteries can be used as the multiple dc voltage sources. This paper focus on phase shifted and level shifted pwm based cascaded multilevel inverter fed induction motor drive. It offer several advantages compared to the conventional 3-phase bridge inverter in terms of lower dv/dt… Expand
