Sažetak
Pulse width modulation (PWM) strategy for a matrix structured three-phase three-level AC to DC boost rectifier is developed. Such approach has been used on purpose to control the input displacement power factor close to unity. The connection between matrix switching function and PWM requirement very well describes all restrictions that occur in the modulation algorithm. This modulation algorithm enables the input displacement factor correction without an input current sensor. The only necessary control variable is the measured displacement angle between input voltage and input current.
