Abstract	Power quality disturbances, such as voltage sags and instantaneous power interruptions, are probably the most frequent and damaging phenomenon in industrial environments. Thus, to improve the sustainability of electrical equipment, the power supplies should tolerate these disturbances. The PFC boost converter operating in CCM is exhaustively used as a first-stage in the power supplies. The average current mode control is the most popular technique and implemented with analog or discrete-time controllers. However, at instantaneous power interruption, the inner controllers go to saturation mode. Consequently, the switching device (MOSFET), of the converter, might be permanently damage when the power returns after voltage interruption. Another current control technique is self-control. In this case, the dynamics controllers are different. Therefore, this paper investigates the operation of the converter at instantaneous power interruption. The average current mode control and self-control are analyzed. Protection strategy is implemented, by FPGA, in a single-phase CCM PFC boost converter. Simulation and experimental results confirm and validate the analysis.
