This thesis investigates the performance-improvement methods of matrix converter drive systems. First, the structure and basic principle of the matrix converter are described. Then, the configuration, characteristics, and mathematical model of the permanent magnet synchronous motor are discussed. Next, the switching strategies of the current regulated method and space vector modulation method are described. After that, a new space vector modulation compensation method, which includes choosing different virtual dc-bus voltage and compensating the duty cycle of the switching states, has been propsed. By using this method, the current ripple and torque pulsation can be reduced.
All of control-loops, including the speed-loop, current-loop, and switching strategy are implemented by a digital signal processor, TMS320LF2407A and a complex programmable logic device, EPM570GT100C4. Finally, experimental results can validate the feasibility and correctness of the proposed drive system.
