Sliding Mode Control: Overview of Its Applications in Power Converters

Abstract

In this article, we present an overview of sliding mode control (SMC) and its applications in power converters. Owing to the distinguished features such as fast dynamic response, robustness, order reduction, and implementation simplicity, SMC is widely studied in power converters. First, we briefly review SMC design. Then, we compare the classical current control and SMC methods for a grid-connected inverter application. Next, we summarize the advantages and disadvantages of SMC. Existing SMC applications in various power converters are presented and a block diagram for each converter topology is given. Finally, we discuss future challenges in SMC.
