Switched-Capacitor Multilevel DC/AC Inverters in Solar Panel Energy Systems

Switched-capacitor multilevel DC/AC inverters will be described in this chapter. For convenience, we call them switched-capacitor inverters or SC inverters (SCIs).

12.1  Introduction

A switched capacitor (SC) is usually manufactured with a switch and a capacitor together [1–6]. It has been used in DC/DC converters for many years. It can be integrated into power semiconductor IC chips. Hence, SC converters have small size and work at high switching frequencies. This technique opened the way to building converters with high power density and attracted the attention of research workers and manufacturers. We were the first to use switched capacitors in DC/AC inverters. ...
