According to development of various devices for high performance, the circuit technologies have been also studied. One of main streams concerns a soft switching technology to mitigate switching stress, leading to the reduction in switching losses or electro-magnetic noise. On the other hand, as a characterized orthodox technology, the existing chopper circuit is used for the electric vehicles, etc...
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...
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.
