High Power Factor and High Efficiency— You Can Have Both

چکیده
Although improving the power-supply power factor (PF) can offer significant and necessary reductions in distribution losses, it is usually assumed that adding an active power-factor correction (PFC) stage will reduce the supply’s internal efficiency. It doesn’t have to be this way. This topic shows that several new system architectures are possible that can minimize system losses, accommodate a wide range of AC line voltages, and meet power-quality requirements.

Nowadays, digital signal processors (DSPs) are appropriate choices for real-time image and video processing in embedded multimedia applications not only due to their superior signal processing performance, but also of the high levels of integration and very low-power consumption. Filtering which consists of multiple addition and multiplication operations, is one of the most fundamental operatio...
متن کاملAn Isolated Off-Line High Power Factor Electrolytic Capacitor-Less LED Driver with Pulsating Output Current
One of the most efficient lighting technology is based on light-emitting diodes (LEDs). Common LED drivers with AC-input (50-60Hz) usually require a bulk electrolytic capacitor to decrease low-frequency ripple in the output. However, the critical element that limits the lifespan of the LED driver is the electrolytic capacitor. An isolated off-line LED driver is proposed in this paper, in which ...

متن کاملDesign Optimization for Total Volume Reduction of Permanent Magnet Synchronous Generators
Permanent magnet synchronous generators (PMSGs) are novel generators which can be used in high-performance wind farms. High efficiency and flexibility in producing electricity from variable rotation make them good candidate for wind power applications. Furthermore, because these kinds of generators have no excitation winding, there is no copper loss on rotor; hence, they can operate at high pow...
متن کاملBioremediation of thermal power plant effluents with chitosan and chitosan nano particels
Water pollution caused by thermal power plant effluent discharges has become a worrisome phenomenon due to its impact on environmental health and safety. Many treatment processes that have been used to remove heavy metals from wastewater are suffered from high cost. Chitosan is a low cost adsorbent which is biodegradable and biocompatible polymer obtained from shrimp biowaste. In the present st...
