RESUMO

Power processors are devices capable to convert a set of voltages, with fixed amplitude and frequency, in other set, with controlled amplitude and frequency. The main function of these processors is to work as an adjustable power supply. The direct power converters are a class of power processors. They have significant advantages compared with the traditional indirect power converters, such as bidirecional power flow, sinusoidal input currents and output voltages, input displacement factor control and compact power circuit. Among the topologies of direct power converters, the matrix converter topology is the most known in the literature. Many control techniques for matrix converters were proposed, but there is not a simple strategy capable of generalize all the control techniques. The objectives of this dissertation are: study the evolution of the matrix converters, present the complete mathematical model of a three-phase matrix converter, propose a generalized escalar modulation strategy, simulate and compare three well-known techniques in the literature with three new techniques discovered from the study of the generalized modulation strategy
