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(More)
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.
For small capacity 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(More)
