SCALAR PULSE WIDTH MODULATION STRATEGIES FOR MATRIX CONVERTERS
27 de junho de 2008 ās 18:04
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.
