中文摘要

本文提出了一种基于谐振开关电容拓扑(RSCT)的48V直流输入可调光LED驱动器。通过引入可变电感(VI)实现模拟调光功能。该拓扑基于经典的RSCT升压双模变换器,在保证宽调光范围的同时,提供了一种简单且高性价比的解决方案。

English Abstract

This paper proposes a new 48-V dc-fed dimmable LED driver based on a resonant-switched-capacitor topology (RSCT), where the analog-based dimming feature is accomplished by means of a variable inductor (VI). The proposed topology is based on the classic RSCT step-up double mode converter and it provides a simple and cost-effective solution while guaranteeing a wide dimming range. In order to implem...

该文献探讨的谐振开关电容拓扑及可变电感控制技术,主要应用于LED驱动领域,与阳光电源的核心光伏逆变器、储能系统及风电变流器业务关联度较低。然而,其提出的高效率、高功率密度变换技术思路,可为阳光电源户用光伏系统中的辅助电源设计或iSolarCloud配套的智能照明/显示模块提供技术参考。建议关注其在小型化、高效率DC-DC变换方面的设计方法,以优化辅助电源系统的成本与体积。
