The system-level value of wide bandgap power semiconductors of higher efficiency, smaller size and weight, and more sustainable energy usage in our power supplies and motor drives is being demonstrated now. Gallium nitride (GaN) power FETs are replacing silicon (Si) power MOSFETs in applications from 48 V to 800 V. Silicon carbide (SiC) is replacing legacy IGBTs in applications … [Read more...] about Practical Realization of GaN’s Capability

Supercapacitor Assisted Surge Absorber Technique: high performance transient surge protectors for consumer electronics
Invention of the transistor in 1947 made a radical change to the path of the development of electronic products and systems. In the mid-1950s, integrated circuits (ICs) started evolving rapidly, creating miniaturized analog, digital and mixed signal circuits. By the 1960s to 1970s, microprocessors, memories and power semiconductors entered the electronic marketplace. During the … [Read more...] about Supercapacitor Assisted Surge Absorber Technique: high performance transient surge protectors for consumer electronics
Hardware Engineer’s Guide to a Brushless-DC Motor Controller
Brushless-dc (BLDC) motors have best-in-class torque to weight ratio, high efficiency, and effective control algorithms, which make them effective solutions in applications requiring high power density, such as cordless power and garden tools, unmanned aerial vehicles (UAV), robotics, and others. Improvements in semiconductor packaging technology, motor control algorithms, and … [Read more...] about Hardware Engineer’s Guide to a Brushless-DC Motor Controller
Expert View: GaN Outperforms Silicon, Enters Mainstream
How does one define ‘main- stream’? In the case of gallium nitride (GaN) power semiconductor technology, we believe that since you can now buy a sleek, 65 W mobile charger using GaN for under $25 on Amazon, it is reasonable to assume that it has been fully accepted by the consumer markets, which—almost by definition—makes it a mainstream product. For more about this … [Read more...] about Expert View: GaN Outperforms Silicon, Enters Mainstream
