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
