A Simple Control Approach for Buck Converters With Current-Constrained Technique

The output voltage tracking problem with overcurrent protection for a pulse width modulation-based dc-dc buck converter is investigated in this brief. On the one hand, large transient current during the start-up phase is required for fast dynamics. On the other hand, overlarge transient current may lead to a risk of hardware damage. Conventionally, this problem is solved by choosing conservative control parameters, while the dynamic performance...
