Abstract
n recent times, intense research has been focused on the performance
enhancement of permanent magnet synchronous motors (PMSM) for
electric vehicle (EV) applications to reduce their torque and current
ripples. Permanent magnet synchronous motors are widely used in
electric vehicle systems due to their high efficiency and high torque
density. To have a good dynamic and transient response, an appropriate
inverter topology is required. In this paper, a five-level inverter fed
PMSM for electric vehicle applications, realized via co-simulation in an
electromagnetic suite environment with a reduced stator winding
current of PMSM via the use of in-phase disposition (PD) pulse width
modulation (PWM) techniques as the control strategy is presented. The
proposed topology minimizes the total harmonic distortion (THD) in
the inverter circuit and the motor fed and also improves the torque
ripples and the steady-state flux when compared to conventional PWM
techniques. A good dynamic response was achieved with less than 10A
stator winding current, zero percent overshoot, and 0.02 second
settling time synchronization. Thus, the stator currents are relatively
low when compared to the conventional PWM. This topology
contribution to the open problem of evolving strategies that can
enhance the performance of electric drive systems used in unmanned
aerial vehicles (UAV), mechatronics, and robotic systems
