Today’s switch-mode power supplies (SMPS) are smaller, more efficient, and lower-cost than ever. The key to their performance is the power switch technologies at their heart – but how should designers choose the right material for this and find the best component to meet their needs?
While silicon is the most widely-known constituent of semiconductors, a new group of wide bandgap (WBG) materials is increasingly finding its way into applications. One example is gallium nitride (

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 modules f

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

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
