This paper proposes the generation of a multilevel 30-sided space vector structure (SVS) from a single DC-link for an open-end induction motor (OEIM) drive. This scheme exhibits the inherent advantages of multilevel inverters like usage of low voltage blocking switches, less dv/dt in phase voltage etc. As the SVS generated is a 30-sided, lower order harmonics till 25th order is eliminated from the motor phase voltage. Linear modulation range is also extended till 99.63 of the base speed as the SVS is closer to a circle. The topology consists of a DC-link fed hybrid 5-level inverter feeding one end of the OEIM and a capacitor fed hybrid 5-level inverter feeding from the other end of the OEIM. Active DC-link fed inverter acts as the only source of active power while the inverter feeding from the other end acts as a switched harmonic filter. Simulation studies and experimental verification of the proposed scheme are performed and presented in this paper. © 2020 IEEE.
