Traditionally, off-the-shelf power inductors have offered the capability to perform a variety of functions and serve many different applications. The same inductor might have served one circuit as a ripple-smoothing element in an LC output filter and as an EMI suppression choke in another.

The power-semiconductor switches used in power supplies and inverters are based on two technologies, namely MOSFETs and IGBTs. MOSFETs can operate at relatively high switching frequencies significantly above 30 kHz but, unlike IGBTs, they have a very large chip surface area.
A new generation of IGBT

The most common options for increasing data-center energy efficiency, including elimination of the PDU (power-distribution unit) and converting to DC power, require disruptive, expensive, and time-consuming

Mobile electronics can be found everywherehomes, hospitals, schools, purses, and pockets. With the explosion in portability, consumers have come to expect and demand long battery life. Energy-efficient
