Abstract
This paper proposes a control algorithm for the power supply to maintain the desired output voltage waveform when the instantaneous power failure occurs. The proposed system switches the control mode between the voltage-controlled and the current-controlled modes in the instantaneous power failure. The proposed control method has little steady-state error and good transient response. The validity of the proposed scheme is investigated through simulation and experimental results.
