    Several research works have been pushed by industry to develop electric vehicles. This study aims at optimizing the cost and energy of the electric powertrain that is based on two in- duction motors supplied by two independent inverters in the conventional case, but this solution is expensive in terms of size and number of power switches. Thanks to its special topology with reduced number of semiconductor switches, the nine switch inverter has been suggested as a substitution to two conventional two level inverters. On the other hand, thanks to the robustness of direct torque control scheme as compared to other vector control methods, (DTC) proves to be a well suited control scheme for electric vehicle applications. Nowadays, the brilliant tech- nology in automotive industry towards regenerative braking is improving, thus bidirectional DC-DC converters are used for capturing the kinetic energy of motor and charging the battery during regenerative mode. In this context, a control of an electric vehicle traction chain based on dual induction motor drive using nine switch inverter is investigated in this report, to study the independency con- trol of nine switch inverter powered motors. Furthermore, the effectiveness of the developed controllers in separating between the flu xan dtorqu econtro lhav ebee nchecked .Likewise ,the regenerative braking has been studied to promote the efficienc yan drealizatio no fenerg ysaving in the electric vehicles. Simulation of these techniques were then carried out using MATLAB/Simulink software and the obtained results analyzed and discussed to confir mth evalidit yo fth epropose dtechniques.
