Summary:In distributed converter topology, where each phase leg is
controlled by a separate module controller, there is an inherent delay
in daisy-chained and ring-type structures. This creates a
synchronization problem in data acquisition and implementation of pulse
width modulation (PWM). Waveforms that predict the effect of the delay
and help define system requirements are presented
