Protection against lightning effects
... This phenomenon also occurs, though to a lesser degree, when there is a strike some distance away, even as far as several hundred metres. For example, a 10 kA lightning current 100 m away will generate a 600 V overvoltage in a 30 m2 loop. The same lightning current in the lightning conductor downcon ...

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.
