A buck–boost-type unity power factor rectifier is proposed in this paper. The main advantage of the proposed rectifier over the conventional buck–boost type is that it can perform input power factor correction (PFC) over a wider voltage conversion range. With a single switch, a fast well-regulated output voltage is achieved with a zero-current switch at turn-on. Moreover, the switch voltage str...

Electricity is one of the basic needs modern human life and already so integrated into everyday life. This understandable given coal's ample resources. Another factor that influences growth coal use plants are designed asa burden because price relatively cheaper. However, existence as fuel for power on decline not renewables. One applications renewable energy potential solar generation technolo...

Mallampati et al, proposed a grading system to anticipate difficult intubation, which considers visualization of faucial pillars, soft palate and base of uvula. 4 The upper lip bite test (ULBT) was proposed as a simple bed side technique by Khan et al, which involves the assessment of jaw subluxation and presence of buck teeth. 9 Savva et al, proposed sternomental distance (distance from the su...

Nobel citation makes clear, Buck and Axel not only and Molecular Pharmacology solved the mystery of the olfactory receptors but, in a University of California, San Francisco remarkable series of subsequent experiments, outlined San Francisco, California 94143 the basic organizational principles of the vertebrate ol2 Howard Hughes Medical Institute factory system. More generally, the discovery o...

In this digest, we will present a methodology that allow us to accommodate the conducted Electromagnetic Interference (EMI) generated by power factor correctors to international standards in the design step. EMI filter design considerations and EMI predictive procedures are presented. The predictive procedures are based in a family of curves that allows us to determine the conducted Electromagn...
