Sumario:This paper describes three different scalar pulse width modulation (PWM) techniques for matrix converters to be compared to two other scalar techniques proposed here. Before exposing all the techniques, a mathematical review of the matrix converters is done to aid the comprehension of this converter. These new techniques use, for synthesizing an output reference voltage, only two input voltages in each switching period. As consequence, the losses of the switching process are expected to be lower than the losses of the other techniques. All techniques presented, but one, have unity displacement factor (DF). To verify the characteristics of these new methods, some simulation results are presented and compared with some simulation results presented by the other methods.
