ABSTRACT
This chapter introduces laddered multilevel DC/AC inverters, which have a simple structure and straightforward operation and are a new development in the DC/AC inverter area and begins with a brief description on progressions. All geometric progressions have a constant ratio between successive terms. Two special series are binary progression and trinary progression. Two new progressions are designed for laddered multilevel inverters. They are Luo progression and Ye progression. The Luo progression is a new series that is different from any existing methods such as arithmetic and geometric progressions. Laddered multilevel DC/AC inverters, super-lift modulated inverters, switched capacitor multilevel DC/AC inverters, and switched inductor multilevel DC/AC inverters have been successfully applied in solar panel energy systems. The solar panel is constructed with a solar cell, the technology of which embraces broad multidisciplinary subject areas. The solar cells are divided into two groups: monocrystalline and multicrystalline silicon wafers.
