The interface between control and powerelectronic converters is commonly an appropriate pulse-pattern generation. Well known concepts like PWM or synchronous pulse patterns have their limits in relative modulation degree or dynamics – a new approach called Assessment- Based Flux Trajectory optimization (AFO) provides excellent performance especially at a low ratio of switching frequency to fundamental frequency. The approach and its general principle will be introduced and the performance results will be compared to a classical PWM pulse pattern generation.
