Abstract

As industries increasingly electrify their processes, it becomes increasingly important to better the dynamic characteristics of DC-DC converters. For step changes in load, bangbang control has been shown to minimize the transition time. Amendments to a boost converter's topology can be made to augment this control law and improve dynamic characteristics. Replacing the inductor with a nonlinear coupled inductor and adding a bleed-off resistor at the output help with step increases and decreases in load respectively. The coupled inductor is used to saturate the inductor core quickly, while the bleed-off resistor is used to get rid of excess energy stored in the converter.
