一种具有RMS电感电流减小和基于延迟零电流检测的四相混合升降压变换器

In this letter, a four-phase hybrid step-up/step-down dc–dc converter with a delay-based zero-current detector (ZCD) is proposed. The proposed power stage operates in step-up or step-down mode depending on the target output voltage. It utilizes hybrid switched-inductor-capacitor and dual-path topologies with multiphase operation to reduce conduction loss due to the dc resistance of the inductor by...
