Abstract: Electrical ac machines have been playing an important role in industry progress during the last few decades. Among the ac drives, permanent magnet synchronous machine (PMSM) drives have been increasingly applied in a wide variety of industrial applications. The reason comes from the advantages . of PMSM over other machines: high power density and efficiency, high torque to inertia ratio, and high reliability.. There are two broad classifications of controlling a PMSM drive: one is the synchronous mode of control and the other is the self controlled mode. In the former mode of control, the machine suffers from hunting oscillations during transients. For a self controlled drive, the air gap flux and the rotor field are always in synchronism and hence there is no hunting in the machine during transients and the dynamic response of the drive is much better. - In this dissertation, an integrated self controlled PMSM drive has been fabricated with a three phase voltage source inverter feeding three phase power to the machine and a single phase PWM converter at the input of the drive.' The PWM converter at the front end draws sinusoidal input current in phase with supply voltage thereby improving, power factor and reducing input current THD. The bidirectional power flow capability of the PWM converter enables regenerative braking of the drive. Constant torque angle control- algorithm is used to drive the voltage source inverter feeding the PMSM under constant flux up to base speed. The simulation of the integrated drive is done using MATLAB-Simulink. The_hardware-of the integrated drive is fabricated and the firing and control signals for the drive are generated by a Digital Signal Processor (DSP) TMS320F2812. Performance investigation of the fabricated self controlled drive is done and the results are documented which show that the drive has appreciable dynamic response.
