Switch mode power supplies (SMPSs) are used in a range of applications as an efficient and effective source of power. This is in major part of their efficiency. For anybody still working on a desktop, look for the fan output in the central processing units (CPU). That’s where the SMPS is. SMPS offers advantages in terms of size, weight, cost, efficiency and overall performance. These have become an accepted part of electronics gadgets. Basically, it is a device in which energy conversion and regulation is provided by power semiconductors that are continuously switching “on” and “off” with high frequency.

Not only there.. They are used almost anywhere as they are far more efficient using much smaller transformers that are switched in high frequency, from few to hundreds of kilohertz. The power supply of your laptop or desktop is a switch mode. Your refrigerator and air condition uses one or more, the applications are endless from very low power to industrial applications. They are also called 'inverters'.

Edit: No they are not called inverters as an inverter transforms a DC current to AC... Switch mode generally convert a DC voltage to a DC of other value... Sorry about that!
