Synopsis:

This paper contains the modelling and simulation result of classical (vector control) field oriented control and Space Vector Pulse Width Modulation (SVPWM) voltage source inverter fed Permanent Magnet Synchronous Motor (PMSM). Permanent magnet motor drives are used in many industrial applications such as driving the robot and CNC machine tool. The precise control of a permanent magnet motor drive is not easy due to the presence of nonlinearities in Permanent magnet motor servo systems, parameter and load torque variations. Advanced pulse width modulation and
control techniques, such as Space Vector Pulse Width Modulation and Field Oriented Control, have been used for the closed-loop control of the system. Next, a model of diode-rectified two-level voltage source inverter is developed for simulations. A comparative study of indirect space vector modulated direct two-level voltage source inverter converter and space vector modulated diode-rectified two-level voltage source inverter is given interms of input/output waveforms to verify that the converter fulfills the two-level voltage source inverter operation.
