Abstract :
This paper presents a new Shunt Active Power Filter (SAPF) that is able to compensate current power quality problems and also to serve as energy backup to the loads in case of power outages. The paper describes the hardware topology, the control system of the SAPF, as well as the energy backup control scheme. Also it describes the power outage detection scheme to trigger the energy backup mode, as well as the grid synchronization after the power restoration. To assess the behavior of the SAPF when compensating power quality problems in transient and steady-state, and during the operation as energy backup system, several simulations were performed.
