摘要

本文提出了一种集成改进型三电平降压变换器(M3-LBC)，以缓解传统三电平降压变换器(3-LBC)固有的不平衡问题。为了实现3-LBC飞行电容电压的自平衡，增加了3个开关和1个电容。该转换器从40-72V的宽范围输入提供12V输出。该样机采用180nm CMOS技术设计，在输入40V、输出电流为~3A时，峰值效率可达~94%。

Integrated Modified Three-level Buck Converter With Flying Capacitor-Voltage Self-Balance

In this study, an integrated modified three-level buck converter (M3-LBC) is demonstrated to alleviate the inherent imbalance issue in the traditional three-level buck converter (3-LBC). To achieve self balance of flying capacitor-voltage of a 3-LBC, three extra switches and one capacitor are added. This proposed converter provides 12V output from a wide range of 40-72V input. The prototype is designed using a 180 nm CMOS technology, with the peak efficiency of ~94% at 40V input and ~3A output current.
