Comparative Analysis of FOC Based Three Level DCMLI Driven PMSM Drive

This paper deals with an comparative analysis of field-oriented control (FOC) based three level diode clamped multilevel inverter (DCMLI) driven Permanent Magnet Synchronous motor (PMSM) drive. The FOC of PMSM is widely used methods for the speed and torque control. The FOC PMSM drive system is designed simulated and implemented using various modulation techniques to calculate the desired torque, speed and stator current. The main disadvantage of Pulse Width Modulation (PWM) & Space Vector Modulation (SVM) are the problem of higher total harmonic distortion (THD) and lower effective DC utilization. In CBSVM, The main advantages of SVM is fast and efficient implementation, without sector determination & work on the effective time relocation algorithm. The Simulation analysis of the novel scheme is carried out by using MATLAB software. The simulation results show that the proposed novel control scheme has a good dynamic response in terms of speed and torque response. It can also reduce the torque ripple and THD of voltage and current gives better motor performance.
