7.5 Summary
This chapter presents a predictive control scheme for a matrix converter that effectively controls the output currents and the reactive input power. The strategy presented allows the input power factor to be regulated by means of a simple and straightforward technique, controlling the phase of the input current in such a way that the converter can work with capacitive, unity, or inductive power factor, according to the requirements of the application.
This method can be easily implemented by taking advantage of the present technologies available in digital signal processors. The high sampling frequency required should not be a problem nowadays and even less in years to come. This control strategy uses, in a convenient way, the discrete nature of power converters and the microprocessors used in their control.
The predictive control scheme is simpler than the classical control scheme for the matrix converter.
