Summary:
Many studies have been devoted to analyze the Zero Average Dynamics (ZAD) strategy for controlling power converters. In this paper the ideal model of the buck converter is analyzed when is controlled by ZAD strategy; however, the analog to digital process is considered in the modeling state, because all signals used to compute the duty cycle pass through analog to digital converter. In particular two di?erent ways to quantize the signals are used. As ZAD-strategy is highly sensitivity to duty cycle values which are computed from the capacitor voltage and inductor current, this communication intends to explain why the experiments are very different from the ideal model results.
