The sliding mode control of Variable Structure Systems has a unique role in control theories. First, the exact mathematical treatment represents numerous interesting challenges for the mathematicians. Secondly, in many cases it can be relatively easy to apply without a deeper understanding of its strong mathematical background and is therefore widely used in the field of power electronics. This paper is intended to constitute a bridge between the exact mathematical description and the engineering applications. The paper presents a practical application of the theory of differential equation with discontinuous right hand side proposed by Filippov for an uninterruptible power supply. Theoretical solutions, system equations, and experimental results are presented.
