Abstract

With the rapidly development of the controller in the electric drive system of electric vehicle (EV), the focus of attention has shifted from designing the controller in the electric drive system of EV to improving the operating efficiency of EV. In this paper, the control method has been studied for the electric drive system of EV, on the basis of which it introduces the compensation method for the dead-time effect of voltage space vector poise width modulation (SVPWM) in the EV. Then, the performance of the compensation method on the dynamic efficiency of the controller in the electric drive system of EV has been analyzed, and the experimental results demonstrate that the dynamic efficiency of the driven system with the SVPWM has been improved by using the dead-time compensation method.
