Wireless energy transfer enables the remote powering and charging of the myriad of battery-powered devices that have infiltrated our daily lives.
Envelope tracking is a power supply technique for improving the energy efficiency of Radio Frequency Power Amplifiers by precisely tracking the power demand, as compared to today’s fixed-power systems. In cell phones use of envelope tracking means longer talk time, and in base stations it means smaller, less expensive amplifiers that consume far less energy and are less expensive to operate.
The quality of sound reproduced by the audio amplifier, measured by THD (Total Harmonic Distortion), DF (damping factor), and IMD (intermodulation distortion) is influenced by the characteristics of the power transistors used.
LiDAR (Light Distancing and Ranging) uses pulsed lasers to rapidly create a three dimensional image or map of a surrounding area.
The continually increasing demand for small, high efficiency, high speed response point of load converters is driving demand for faster, more efficient power switches.
Emerging computing applications demand more power in much smaller form factors. In addition to the expanding needs of the server market, some of the most challenging applications are multiuser gaming systems, autonomous cars, artificial intelligence, and cryptocurrency mining.
LiDAR (Light Distancing and Ranging) is used in augmented reality to create a three dimensional image or map of a surrounding area.
Data centers consume vast amounts of electrical energy. Operating power for these centers runs from megawatts to tens of megawatts. Power conversion design today in the data center is focused on improving energy efficiency and reducing operation costs.
Resolution is a critical attribute of all medical imaging devices, such as sonograms, CAT scans, and MRI. eGaN FETs and ICs increase the speed and precision with which imaging equipment can conduct scanning measurements. The small size and efficiency of eGaN® FETs improves resolution of data collected, while lowering operating power resulting in faster imagery.
The smallest, most cost effective and highest efficiency non-isolated 48 V – 12 V converter, suitable for high-performance computing and telecommunication applications, can be achieved by employing eGaN FETs such as the EPC2045.
Power converters used in harsh environments, such as space, high altitude flight, or high reliability military applications must be resistant to damage or malfunctions caused by radiation.
Automotive electronics can now take full advantage of the improved efficiency, speed, smaller size, and lower cost of enhancement-mode gallium nitride (eGaN) devices. Already, several large applications where GaN has significant advantages over the aging silicon MOSFET have emerged, particularly at the 48 V input node.
