中文摘要

开关电容(SC)变换器在为微处理器提供快速、精细的电压方面具有显著优势。然而,电压转换比(VCR)过渡过程中产生的损耗往往被忽视,这会导致效率大幅下降。本文提出了一种简单且精确的模型,用于估算SC变换器在VCR过渡期间的能量损耗,并探讨了降低该损耗的有效技术。

English Abstract

Switched-capacitor (SC) converters have numerous advantages in supplying fast and fine-grained voltages to microprocessors. However, the losses associated with the voltage conversion ratio (VCR) transition, which has not been investigated in detail, may cause a significant efficiency drop. This letter presents a simple and accurate model for estimating energy losses during the VCR transition of ma...
