Abstract

This paper presents the design of a DC-AC power converter controller that bears the same benefits of a sliding mode controller but with the advantage of a fixedfrequency control signal. The controller is based on the imposition of zero averaged value of the sliding surface in each switching cycle. A keypoint of the presented controller is the calculation of the sliding surface’s derivative which in the present paper is obtained using an estimation algorithm introduced by Levant in 1998.
