title = "Real-Time Calculation Method for Single-Phase Multilevel Converters Based on Phase-Shifted Carrier Pulsewidth Modulation",
abstract = "The time delay caused by the digital computation and the update of duty cycle tends to worsen the dynamic performance of digitally controlled power converters. This paper proposes a real-time calculation method for multilevel converters with the phase-shifted carrier pulsewidth modulation (PSC-PWM) to eliminate the time delay of the digital controller without the loss of duty cycle. A proposed sampling method, which samples the current and voltage at the intersections of all phase shifted carriers, is used alternately with the traditional regular sampling method following a selection rule, which is elaborated in theory. Experimental results verify that the proposed real-time calculation method effectively improves the bandwidth of the control system.",
