| Abstract |
A multilevel inverter scheme with reduced number of switches using a single DC-link for open-endinduction motor drives (OEIM) is presented in this paper. The total inverter system with OEIM yieldsvoltage space vector (SV) locations alike to a 5-Level inverter. This proposed system is obtained bysupplying OEIM with 3-Level inverter from one side and capacitor fed 2-Level inverter from anotherside. The capacitor of the 2-Level inverter is balanced by space vector redundancy to its nominal voltage of Vdc/4 where Vdc is the DC link voltage and the flying capacitors in 3-Level inverter is balanced by pole voltage redundancy to its nominal voltage of Vdc/2. The simulation and hardware results for steady and transient state operation are also presented in this paper. |
