Copper losses
... Eddy current, and hysteresis losses are called ‘iron losses’. This type of loss is a magnetic loss. The eddy current, particularly within a material such as iron, can cause quite a large increase in temperature, and consequent power loss. Solution = laminated cores (these reduce the losses) Hysteres ...

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.
