Simultaneous space vector modulation direct torque control of two induction motors used in electric vehicles by a nine-switch inverter

In this paper, a novel two output nine switch-inverter is proposed in order to
increase the synchronization speed of induction motors used in electric vehicles
(EVs) while improving the efficiency and controllability of the system. The
number of switches in the proposed inverter is reduced by 25% compared to
double six-switch inverters which conventionally used in EVs. The main
characteristics of the considered inverter can be noted as follows: sinusoidal
input and outputs, unity output power factor, and specifically, low construction
cost due to active switch number reduction. The classical direct torque control
method causes torque ripple and speed fluctuations. Therefore, in order to
increase accuracy and dynamics of drive system, the SVM-DTC method is
proposed, leading to less torque ripple and constant switching frequency. The
obtained torque ripple is 2% which is less than the existing structures In order
to illustrate advantages of the proposed approach, performance of the EVs in
the standard cycles is evaluated.
