The injection of sinusoidal current to an electrical
grid is nowadays possible with the use of active power filters
(APFs).With quasi-steady-state (QSS) nonlinear controllers, these
power filters provide low grid-current-harmonic content with
simple-control analog implementation. This paper focuses on the
design of a QSS nonlinear controller for a single-phase APF.
A complete analysis based on the sliding-mode-control theory
is given. From the analysis, a set of control-design guidelines
is presented to select the gains and parameters of the control
scheme. Selected experimental results are reported to validate the
theoretical design procedure.
