Permanent Magnet Synchronous Motors (PMSM) have demonstrated their usability in automotive and other files in the recent years. A low torque ripple PMSM drive proves to be suitable for power steering and hybrid vehicle applications. This paper presents analysis of two different techniques for low torque ripple PMSM drive using DTC and performs a comparative analysis of the ripples. The complete PMSM drives are modeled using MatLab Simulink environment where different blocks are interconnected to form the complete test setup. Input torque is applied to check the parameters of the drive including the ripples. Analysis shows that the technique Dual Inverter gives 6.442% of ripples whereas the SVPWM technique affects the output in terms of ripples by 0.9762%. The theoretical analyses and simulation results indicates that SVPWM technique can reduce the flux linkage and torque ripple in a large extent and have a better dynamic and static performance as compare to dual inverter technique
