Effect of Feed Forward on Pfc Based of Single-Phase Uninterruptible Power Supply
(International Organization on 'Technical and Physical Problems of Engineering', 2020) Mamizadeh, A.; Genc, N.; Hama, S.O.
An uninterruptible power supply (UPS) is used to prevent interruption by providing energy to the load for a certain period of time despite grid interruptions. The main points to consider when designing any UPS system are the input power factor ratio and distortion harmonics. For this reason, UPSs are generally designed with power factor corrected (PFC) circuits. PFC based UPSs eliminate harmonics originating from the load and enable them to draw currents with high power factor ratio from the grid. PFC controllers with feed forward content are used to reduce the effect of input voltage dynamics in active PFC circuits. In this study, the effects of the feed forward PFC circuit on UPS were investigated. In the proposed study, Matlab/Simulink program was used, and the results obtained from here were evaluated. © 2020, International Organization on 'Technical and Physical Problems of Engineering'.
