Efficiency is the name of the game in the design of power supplies. This is a major reason why switch-mode power supplies (SMPSs) are chosen for power-supply designs. However, even SMPSs have their ...

Regular on/off switches rely on fingers and springs to bring bits of wire together or apart. When the wires touch, electrons flow from one to the other, and your computer/nightlight/sock warmer is on.

Perovskites have received a lot of attention as semiconductor materials for solar cells because they’re efficient, inexpensive, and easy to make. But designing transistors, the fundamental component ...

For good reason, CMOS chip designers pay careful attention to the equation that governs dynamic power consumption: ½CV2f. We have seen the benefit over the past two or three decades, as supply ...

The Manchester University team that first isolated graphene has discovered a way of introducing a band gap into the material that makes it a much more promising candidate for building transistors.

Efficient Power Conversion has developed a series of gallium nitride transistors able to operate in switching applications above 10 MHz. The devices are suited for envelope tracking in RF power ...

Editor’s note: We bring you Chapter 5: Buck Converters of”GaN Transistors for Efficient Power Conversion,” published by Power Conversion Publications. The authors delve into various buck converter ...

A University at Buffalo team has proposed a new form of power MOSFET transistor that can handle incredibly high voltages with minimal thickness, heralding an efficiency increase in the power ...
