Some critical aspects in sliding mode control design for the boost inverter

In this paper some critical aspects for the design of sliding mode control applied to the boost inverter are presented, including a theoretical analysis and the implementation of the control strategy. The SMC has been proposed in different papers as an option to improve the dynamic response of the electronics circuit. In this paper several design issues related to the theory as well as to the practical implementation of the SMC are discussed. A converter, which has excellent features like boost and inverting functions at the same time (boost inverter), is used as an example design.
