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...
In recent years, various clean energies have been developed, and their practical use is expected for a fuel cell, a solar cell and so on. Since these are low voltage, voltage boost is needed in practical applications. This paper proposes a novel converter which is used for voltage boost using LC resonance. The switch is turned-on and off at the instant when current becomes zero due to LC resonance,...
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 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...
