This paper deals with the design, control, and implementation of a three-phase ac–ac mobile utility power supply using a matrix converter for airplane servicing applications. Using a matrix converter as a compact direct ac-to-ac converter can provide savings in terms of the size and cost of a mobile power supply compared to common back-to-back converters. Furthermore, using the proposed direct matrix converter eliminates the need for bulky electrolytic capacitors and increases the system’s reliability and lifetime. A finite control set model predictive control is used to generate a high-quality 115 V/400 Hz output voltage and a low-harmonic-distortion source current with a unity input power factor for various load conditions, including balanced, unbalanced, linear, and nonlinear loads. The predictive strategy is used to control the output voltage and source current for each possible switching state in order to simultaneously track the references. To achieve a further reduction in the system’s size and cost, an active damping strategy is used to compensate for the instability caused by the input filter in contrast to the passive method. Experimental tests were conducted on a prototype matrix converter to validate the performance of the proposed control strategy.

Vector Modulation

In this p aper, Matrix Converter is which converts the AC to AC in a single stage. The merits of the matrix converter is its able to deliver variable output voltage with unrestricted input and output frequency, the lack of electrolytic capacitors, and the potential to raise the power density, decrease the size, less weight and better input power quality. In whatever way, application of these converters are restricted because of some issues such as different control strategies, high susceptibility to input power disturbances, common mode voltage effects and less voltage transfer ratio. Recently, matrix converters have gained a resurgence of importance due to the improvements in the semiconductor device industry and the increasing of processor technologies, which promises real implementation of matrix converters in the control of drives. The real effect of indirect space vector modulation scheme for very sparse matrix converter performance will be measures by testing of computationally for using indirect space vector modulation strategies with the passive R load and active load .
