Abstract

Current-mode control is used in Switched-Mode Power Supplies (SMPSs) due to its high stability and quick response. Moreover, peak current-mode control, as one of the current-mode control techniques is often used due to its ease of design and capability of overcurrent protection. However, peak current-mode control sometimes makes output oscillations in certain conditions. Accordingly, SMPSs designers often use slope compensation to prevent output oscillation. However, it has some challenges such as design complexity and delayed response. Therefore, in this research, the authors derived a conditional expression to replace the use of slope compensation based on multi-cycle digital control. The proposed quantity along with its derivation is provided in this manuscript. Furthermore, the carried-out investigations validate its applicability.
