“…Due to the different dynamic equations of the current in each of the aforementioned machine types, control parameters and equations differ in each [34], [45]. Despite various control and modulation techniques for different machines, there are usually four general stages in the operational structure of a conventional cascade-controlled multilevel drive: Outer control loop, inner control loop, modulator, and a mid-stage which mostly deals with the capacitor voltage balancing [34].…”

Traction inverter has been the subject of many studies due to its essential role in the proper performance of the drive system. With the recent trend in increasing the input voltage in battery-powered electric vehicles, multilevel inverters have been proposed in the literature as a promising substitute for conventional twolevel traction inverters. A critical aspect of utilizing multilevel structures is employing proper control and modulation techniques. The control system structure must be capable of handling a number of key issues, like capacitor voltage balancing and equal power loss sharing, which arise in multilevel topologies. This paper presents a review of the present-day traction drive systems in the industry, control and modulation techniques for multilevel structures in the inverters, as well as the principal challenges that need to be addressed in the control stage of the multilevel traction inverter. A comparison has been made between different methods based on the most important criteria and requirements of the traction drive system. Finally, future trends in this application are presented and some suggestions have been made for the next generation of traction drives.

 Calculation of the desired motor requirement for an electric vehicle  Prevention of the long analysis duration by using desing of experiment  Optimization by defining the critical motor design parametersIn this study, electrical vehicle (EV) technologies, vehicle dynamic, the parameters of asynchronous motor were investigated. The performance requirements for a passenger car were calculated from the equations of vehicle dynamic. The performance characteristics of asynchronous motor were evaluated. To achieve the desired motor performance requirements, trivial parameters for asynchronous motor were eliminated by Taguchi's method. After the defining of critical parameters for asynchronous motor, the parameters of asynchronous motor were optimized. As a result, using proposed method which is given in Figure A (Taguchi method and related standard deviation value) has provided to avoid waste of time from long analysis time. Figure A. The diagram of proposed methodPurpose: The purpose of this study is to modify the required design parameters to ensure that a default asynchronous motor can meet the desired engine performance requirements. Theory and Methods:By using the Taguchi method and the related standard deviation value, the parameters of the critical motor design are determined. Then, considering the critical design parameters, the default asynchronous motor is optimized to develop the desired electric motor. Results:The determination of 6 critical design parameters and the optimization of the desired engine were carried out by the proposed method. Conclusion:The long analysis duration and time wasting for all the parameters of the asynchronous motor were prevented by using proposed method.
