在过去的十年中，电力电子学的主要发展方向之一是发展无电感和变压器的开关模式转换器。重量轻、体积小、功率密度高是这些转换器在功率级仅使用开关和电容器的结果。因此，它们是移动电子系统(例如，蜂窝电话、个人数字助理等)的理想电源。开关电容(SC)转换器具有高电压转换比，有望应对21世纪的挑战，如EMI排放低的高效转换器，以及实现电压陡峭降压(至3V甚至更小的集成电路电源电压)或汽车行业或电信行业互联网服务的电压陡增的能力。本文是对SC变流器研究和设计的主要成果的指导。
One of the main orientations in power electronics in the last decade has been the development of switching-mode converters without inductors and transformers. Light weight, small size and high power density are the result of using only switches and capacitors in the power stage of these converters. Thus, they serve as ideal power supplies for mobile electronic systems (e.g. cellular phones, personal digital assistants, and so forth). Switched-capacitor (SC) converters, with their large voltage conversion ratio, promise to be a response to such challenges of the 21st century as high-efficiency converters with low EMI emissions and the ability to realize steep step-down of the voltage (to 3 V or even a smaller supply voltage for integrated circuits) or steep step-up of the voltage for automotive industry or Internet services in the telecom industry. This paper is a tutorial of the main results in SC-converter research and design.
