Abstract :
Digital peak voltage (DPV) control technique with single-edge and double-edge modulation methods is studied in this paper, and it is studied on buck converter. The different control laws for each modulation method are derived and compared. Small-signal analysis is further performed with comparison on the different modulation methods, and the corresponding Bode-graphs of ac small signal transfer functions are also given to show the difference among these different modulation methods.
