Abstarct: In today's world, reducing volume and weight is one of the ideals of any system. In the power electronic world, the matrix converters has taken on a large scale due to their dimensions and size. Among them, two-bridge matrix converters due to their capabilities in reducing the number of switches and reducing the volume and weight of the elements, as well as due to high reliability and the ability to adjust the input power factor to one and the ability to transfer power in both directions and waveforms. High quality output and input are taken into consideration. In this dissertation, using duplicate matrix converters and spatial vector control method, which have high quality waveforms with low harmonic content and the ability to adjust the power factor at the input, compared to other control methods in matrix converters. On the other hand, in the control part of the simulated circuit, in addition to the usual PI controllers, a fuzzy logic controller is used, which causes better quality of output waveforms than the PI controller, which is one of the advantages of this design and simulation over similar designs. In matrix converters, especially doped type, the variety of switching algorithms in the simulation causes the quality of signals, which in this paper, by using the appropriate switching algorithm, the desired signal is obtained. In the simulations performed in this dissertation, it was found that using the spatial vector control method, there is the best output quality and the least changes in terms of load change and input voltage change. On the other hand, with the fuzzy logic controller, the output amplitude was achieved with the least possible ripple. So that the output voltage THD was obtained in the doped matrix converter with 12 switches of 5.98% for the fuzzy logic controller versus 6.4% for the PI controller.
