Abstract
This paper considers the connection between switching matrix function and pulse width modulation algorithm with emphasis on the unity power factor correction requirements for three-phase three-level AC to DC converter. Based on the switching matrix converter theory, the switching sequences for PWM of the three-phase three-level AC to DC converter (rectifier) have been developed. Such an approach enables the input displacement factor correction without an input current sensor. The necessary control variable is only the measured displacement angle between the input voltage and the input current.
