Sliding mode control of a single-phase LCL full-bridge rectifier

Abstract

This paper presents a dynamic analysis and the control design for a singe-phase full bridge recti¿er with a LCL ¿lter. The control algorithm is based on the sliding mode control techniques that provides good tracking performances and robustness against parameter variations. The control design also considers the connection to a non ideal power network with a grid impedance as well as higher harmonics components in the voltage. The control law has been tested in numerical simulations with satisfactory results (also in the case of non ideal power grid).
