Single-phase shunt active power filter, hysteresis-current control, switching frequency, DSP.
In this paper, single-phase shunt active power filter (APF) controlled using hysteresis-current control is studied. A proposition to use the limitation on the maximum switching over frequency of the power devices is made. This limitation increases stability to electromagnetic influences and facilitates a filtration of the radio interference to the source network. In the paper, there are attached computer simulations’ results and experimental oscilogrammes from the filter operation together with a combination of load – linear (active inductive) and non linear (single-phase bridge uncontrolled rectifier with capacitive load). The APF’s control is based on DSP TMS320LF2407.
