This thesis investigates the design and implementation of a full-digital matrix converter for PMSM drive systems. First, the structure, characteristics, and mathematical model of the permanent magnet synchronous motor are discussed. Next, a new control strategy is proposed to extend the ride-through time when the power of the matrix converter is interrupted. The implemented system uses a digital signal processor, TMS-320-LF-2407A, and a CPLD, EPM-570-GT-100-C4, to achieve the current and speed control. As a result, the hardware is simple. Experimental results validate the theoretical analysis. In addition, satisfactory transient responses, load disturbance responses, and extended ride-through interval are obtained.
