Classification and Comparison of BPFC Techniques: A Review
نویسندگان
چکیده
Power factor correction (PFC) techniques play an important role in green power and energy-saving technology. Based on conventional boost PFC, many novel topologies and control strategies of bridgeless PFC(BPFC) have been proposed, and BPFC reduces the number of devices, the losses and improves the power density as well. In this paper, it discusses and investigates a variety of low conduction losses and high power factor performance of the BPFC topological structures and identifies their merits and limitations by comparing and analysing bridgeless boost PFC,bridgeless buck PFC ,bridgeless sepic PFC and Bridgeless cuk PFC. And the trends of bridgeless PFC techniques are analyzed in the meantime. For the selection, application, and the later structural optimization of Bridgeless PFC techniques which are used in the smart grid, distributed energy and green power and other equipments.. Streszczenie. W artykule przedstawiono omówienie badań nad bezmostkowym korektorem współczynnika mocy, mających na celu porównanie strat przewodzenia i skuteczności działania, dla różnych topologii układu. W pracy określono zalety i ograniczenia poszczególnych architektur oraz ich ewolucję. Porównano ich zastosowanie do sieci inteligentnych, energetyki rozproszonej i odnawialnej. (Przegląd i porównanie bezmostkowych korektorów współczynnika mocy).

متن کاملA comprehensive experimental comparison of the aggregation techniques for face recognition
In face recognition, one of the most important problems to tackle is a large amount of data and the redundancy of information contained in facial images. There are numerous approaches attempting to reduce this redundancy. One of them is information aggregation based on the results of classifiers built on selected facial areas being the most salient regions from the point of view of classificati...

متن کاملImmunodepression by Rowson-Parr virus in mice: effect of Rowson-Parr virus and Friend leukemia complex infections on background antibody-forming cells to various erythrocytes.
The numbers of background antibody-forming cells (BPFC) toward erythrocytes of various species present in the lymphoid organs of unimmunized susceptible BALB/c and resistant C57BL/6 mice were investigated at various times after infection with Friend leukemia complex (FLC) or Rowson-Parr virus (RPV). Both virus preparations induced an increase of BPFC numbers in both animal strains, but the rate...
