Introduction of some design aspects for improved performance of the DC/AC induction motor converter

The increasing trend of DC/AC induction motor converters implementation in a wide range of driving applications is becoming a fact that could not be neglected any more. This fact challenges the designers of the DC/AC induction motor converters to constantly seek performance improvements and cost reductions on an everyday basis. The paper describes some of the design improvements of a DC/AC induction motor converter for use in light commercial electrical vehicles. The implementation of design changes is based on electrical analysis, simulation results and also on the previous prototype testing. The goal of design activity presented in the paper is a design of an improved DC/AC induction motor converter with higher performance, enhanced reliability and optimized production cost. The paper concludes with a proposal of a new DC/AC induction motor converter design and concludes with some simulation results.
