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 a little difficult to obtain the lower dc voltage below the one obtained from input ac supply voltage without transformer or switching operations. Those operations can be implemented by passive devices due to fabrication of electrolytic capacitors. The results are confirmed by the theoretical and experimental implementations.
Various rectifier circuits such as those for consumer electronics and appliances, rectifier circuits of the capacitor input type are generally used. The various harmonics generated within such a power system become a serious problem. Various studies to reduce these effects have been presented so far. However, most of these employ switching devices, such as MOSFETs and the like. Removing the need for...

Some papers of power converters that interface between photovoltaic arrays and a.c. utility system have been reported [1]-[3]. Some innovative utility-interactive power conditioning systems have been also studied [4],[5]. The characteristics of these systems lie in the fact that a full wave rectified current waveform is generated from the d.c. source and converted into a low distortion sinusoidal...
Various non-linear semiconductor circuits have been used in consumer electronics and industrial electronics. It is well known that rectifier circuits such as these can generate various harmonics within the power system. Because of this, several different power factor correction circuits have been proposed and studied. These methods are designed to improve the input current to a sinusoidal waveform...
