Modeling and simulation of a boost DC/AC inverter fed induction motor drive

Single-stage three-phase boost dc/ac inverters can provide sinusoidal ac output voltages which are greater than input dc voltage without needing an intermediate dc voltage boost stage. Such a topology is cost-effective due to reduced switch count and it is suitable for compact design These unique features of this type of inverter makes it a suitable choice in many applications such as uninterruptible power supplies, variable speed ac drives, and some distributed power generation schemes. This paper aims to investigate the performance of the inverter in variable-speed control of an induction motor through the simulation models. The simulation results obtained from a three-phase boost dc/ac inverter controlled induction motor drive system are obtained from mathematical models and presented in this paper.
