Summary This article presents an experimental evaluation of a three‐phase induction motor drive during pre‐fault and post‐fault operation. A three‐level boost converter is used at the front end of a two‐level voltage source inverter with a current control algorithm, and a predictive torque control is used for induction motor drive. This topology retains the normal operation under open‐circuit or short‐circuit of devices in any one of the inverter legs, and also the dc‐link voltage across the capacitors is balanced. The merits of the proposed scheme are highlighted and compared with existing fault‐tolerant converter topology (B4) using simulation and experimental results. Furthermore, simulation and experimental results of the proposed scheme in the field weakening region are presented to examine the drive operation above base speed.
