ABSTRACT
This chapter describes a new technique for improving the efficiency of the sliding mode controller that is used to manage the photovoltaic (PV) energy in an autonomous shunt active power filter (APF). It aims to improve the reference current for compensating harmonics, a method to limit the switching frequency. The APF is an efficient solution to solve the problems created by nonlinear loads. In an APF application, the dynamic performance of the sliding mode control will also depend on the algorithm used for identifying the current harmonics. Active power losses in the active filter are the main factors that may change the voltage. Under poor PV power generation conditions, the utility source supplies the active power to the load directly. A maximum power point tracker is used for extracting the maximum power from the solar PV module and transferring that power to the load.
