  • A buck converter is a step-down DC to DC converter. Its design is similar to the step-up boost converter, and like the boost converter it is a switched-mode power supply that uses two switches (a transistor and a diode), an inductor and a capacitor. The simplest way to reduce the voltage of a DC supply is to use a linear regulator (such as a 7805), but linear regulators waste energy as they operate by dissipating excess power as heat.

  • The switching regulator is increasing in popularity because it offers the advantages of higher power conversion efficiency and increased design flexibility (multiple output voltages of different polarities can be generated from a single input voltage). This paper will detail the operating principles of the four most commonly used switching converter types: Buck: used the reduce a DC voltage to a lower DC voltage. Boost: provides an output voltage that is higher than the input. Buck-Boost (invert): an output voltage is generated opposite in polarity to the input....

  • In this chapter, we review power electronic converters used in ASDs with induction motors. Various types of rectifiers providing the dc supply voltage for inverters feeding the motors are presented, and we describe voltage source inverters, including three-level and soft-switching inverters, and current source inverters. Control methods for inverters, with a stress on the use of voltage space vectors, are illustrated. Finally, we outline undesirable side effects of the switching operation of power converters.

  • Computers make use of relatively short parallel connections between interior components, but use a serial bus to convert signals for most external communications.In a parallel connection, it is wrong to assume that the 8 bits leaving the sender at the same time arrive at the receiver at the same time. Rather, some of the bits get there later than others. This is known as clock skew.

  • Practical TCP/IP and Ethernet Networking- P5: The transmitter encodes the information into a suitable form to be transmitted over the communications channel. The communications channel moves this signal as electromagnetic energy from the source to one or more destination receivers. The channel may convert this energy from one form to another, such as electrical to optical signals, whilst maintaining the integrity of the information so the recipient can understand the message sent by the transmitter....

  • Jianchao Wang East Isle Technologies Inc., Setauket, NY 11733, USA Abstract—In this paper, we consider cost-effective designs of wavelength division multiplexing (WDM) optical switching networks for current and future generation communication systems. Based on different target applications: we categorize WDM optical switching networks into two connection models: the wavelength-based model and the fiberlink-based model. Most of existing WDM optical switching networks belong to the first category.

  • AC motors convert AC electrical energy to Mechanical energy. AC motors: the armature of rotor is a magnet (different to DC motors). the stator is formed by electromagnets (like in DC motors). Effects of AC Supply on Magnetic Poles Consider the rotor to be a permanent magnet. Current flowing through conductors energize the magnets and develop N and S poles. The strength of electromagnets depends on current. First half cycle current flows in one direction. Second half cycle it flows in opposite direction...

  • Methionine (Met) is an essential amino acid and the only sub-strate for synthesis of S-adenosylmethionine (AdoMet) that is the main substrate for multiple intracellular methylases. There are two modes of Met metabolism in liver. In case of its dietary restriction Met can be metabolized via conservative remethylation cycle. In case of Met excess (high [Met]) it is mostly converted to cysteine via transsulfuration pathway.
