Introduction The thermoelectricity was discovered in 1821 by Thomas Seebeck where a continuously flowing current was created when two wires of different materials were joined together and heated at one end. This is known as the Seebeck effect (Fig.1). The Seebeck effect has two main applications i.e ...

Buck converter
A buck converter is a voltage step down and current step up converter.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. Buck converters, on the other hand, can be remarkably efficient (95% or higher for integrated circuits), making them useful for tasks such as converting the main voltage in a computer (12V in a desktop, 12-24V in a laptop) down to the 0.8-1.8V needed by the processor.
