Hybrid 5-level inverter fed induction motor drive

摘要

Recently multilevel inverters (MLI) gained researchers interest due to efficient power conversion with multiple voltage steps resulting in improved power quality, reduced switching losses, higher electromagnetic compatibility and better voltage capability. This paper presents a three phase five level hybrid H-bridge inverter for effective control of induction motor drive. Space Vector Pulse Width Modulation (SVPWM) control scheme is proposed for the hybrid H-bridge multilevel inverter fed induction motor drive. The implementation of the SVPWM technique to Hybrid MLI was simulated in MATLAB/ Simulink environment and its results are presented.
