Integrated switched-capacitor DC-DC converters for high-density capacitive energy storage

Storing sufficient electrical energy is the bottleneck in a growing number of applications. Traditionally, a battery is used for this. However, being able to store energy on a capacitor would enable a lot of small, low-power devices that need to harvest their energy from the environment. In this tutorial, I will first introduce the concept of high-density capacitive energy storage. Then, I will discuss in detail how a switched-capacitor DC-DC converter is the most critical building block in such an energy storage system. I will explain how it is designed, what are the performance limits and what the current state-of-the-art is. For the energy storage application specifically, I will introduce a design methodology. This tutorial will thus cover the basics of switched-capacitor DC-DC converter design as well as a specific approach for energy storage.
