19.2 A Three-Mode Single-Inductor Four-Quadrant Converter Achieving 94.6% Peak Efficiency with Seamless Zero-Crossing
Abstract
This paper presents a three-mode single-inductor four-quadrant converter with 94.6% peak efficiency for electrochromic smart windows. It supports a 5 to 12V input, a −5 to +5V output and a −3 to 3A load current, achieving full four-quadrant operation by employing buck/boost, inverting buck/boost and auxiliary transition modes. This integrated converter enables seamless zero-crossing and mode switching with a single inductor, thus resulting in a compact, low-cost, and low-complexity system.
