It is well known that non-linear rectifiers generate various harmonics in the power system. To improve those harmonic problems, a lot of original PFC circuits have been proposed so far. Among these, Takahashi, et al, have proposed a PFC scheme using single switching device for single phase boost chopper. For a buck chopper, however, it is difficult to realize the buck chopper in a usual way using...
Nonlinear rectifier circuits, having capacitors or inductors, are generally used as rectifier circuits, such as those in consumer electronics and appliances. It is known that such rectifiers generate various harmonics in the power system. To reduce these harmonic problems, various original PFC (Power Factor Correction) circuits have been proposed. Amongst these, Prasad-Ziogas, et al, have proposed...
It is well known that non-linear circuits such as various rectifiers generate harmonics in the power system. To improve those harmonic problems, various PFC circuits have been proposed so far. Among these, Takahashi have proposed a PFC scheme using a LC filter without switching devices. This method makes a PFC effect by widening conduction period using the operations of capacitors and inductor. On...
