Harsh environments are a reality for many electrical systems used in motor control or solenoid control applications. The electronics that control motors and solenoids are by necessity in close proximity to the high currents and voltages used to create the physical movement required by the end application.
In addition
It should come as no surprise to anyone that the continuing adoption of Digital Power System Management (DPSM) within the communications and computer industries continues to be driven, in large part, to the high current levels demanded by the sub-20nm ASICs and/or FPGAs that are at the core of their system architecture. By
Working in the industry, we live very close to the developments that are advancing our technology and the systems based upon them. We see nascent science turn into rough prototypes and then into finished products on a regular basis. We are familiar, even if not comfortable, with the rapid pace of progress and ho
Building on the new commitments to the Global Lighting Challenge announced last week during the Clean Energy Ministerial, the Energy Department is announcing funding for nine research and development projects that will support solid-state lighting (SSL) core technology research, product development, and manufacturing re
Portable electronics devices (such as smartphones) are having more and more functionality squeezed into them all the time. Simultaneously, there are exacting pressures being placed upon engineers to lengthen the period these devices can last between battery recharges and bring device models to market with sleeker fo

There have been several comparisons of eGaN FETs with silicon MOSFETs in a variety of applications, including hard-switched, soft-switched, and high-frequency power conversion. These studies have shown that eGaN FETs have large efficiency and power density advantages over silicon MOSFETs. Here we’ll focus on
At APEC 2016 it became abundantly clear to the industry that GaN transistors are here, they're now, and they're proliferating. GaN Systems, EPC, Transphorm, Panasonic, Infineon, Texas Instruments, and other manufacturers and developers all displayed GaN products in varying readiness, from existing only on P
In this article we’ll show how a third way of defining average current leads to an infinite gain of the modulator gain for current-mode systems. Another simple derivation produces a fourth expression for the modulator gain, thus completing the set of gains to be found in the literature.
