چکیده
This paper presents a monolithic GaN driver with deadtime generator (DTG) for half-bridge DC-DC buck converters. The proposed integrated circuits (ICs) were fabricated in 3 µm enhancement-mode MIS-HEMTs process. DTG converter can operate at 250°C large gate swing of 10 V, and it exhibits maximum efficiency 80% high temperatures, VIN= 30 V 100 kHz. requires one control signal generates fewer than 0.13 µs temperatures up to 250°C. is compared an without (w/o) under various conditions. At the optimized shows better performance w/o load currents, terms smaller voltage overshoots as well. work demonstrates simple method temperature (HT) power

Monolithic Integration of GaN Transistors for Higher Efficiency and Power Density in DC-DC Converters
Power converters are constantly trending towards higher output power, higher efficiency, and higher power density. To provide improved performance better power devices are required. For silicon (Si) power devices, the gains in performance have slowed as the technology has matured and approaches its theoretical limits [1]. Gallium nitride (GaN) devices have emerged as a possible replacement for ...

متن کاملImproved InGaN/GaN light-emitting diodes with a p-GaN/n-GaN/p-GaN/n-GaN/p-GaN current-spreading layer.
This work reports both experimental and theoretical studies on the InGaN/GaN light-emitting diodes (LEDs) with optical output power and external quantum efficiency (EQE) levels substantially enhanced by incorporating p-GaN/n-GaN/p-GaN/n-GaN/p-GaN (PNPNP-GaN) current spreading layers in p-GaN. Each thin n-GaN layer sandwiched in the PNPNP-GaN structure is completely depleted due to the built-in ...
متن کاملAPE-GAN: Adversarial Perturbation Elimination with GAN
Although neural networks could achieve state-of-the-art performance while recongnizing images, they often suffer a tremendous defeat from adversarial examples–inputs generated by utilizing imperceptible but intentional perturbation to clean samples from the datasets. How to defense against adversarial examples is an important problem which is well worth researching. So far, very few methods hav...
متن کاملOn the effect of N-GaN/P-GaN/N-GaN/P-GaN/N-GaN built-in junctions in the n-GaN layer for InGaN/GaN light-emitting diodes.
N-GaN/P-GaN/N-GaN/P-GaN/N-GaN (NPNPN-GaN) junctions embedded between the n-GaN region and multiple quantum wells (MQWs) are systematically studied both experimentally and theoretically to increase the performance of InGaN/GaN light emitting diodes (LEDs) in this work. In the proposed architecture, each thin P-GaN layer sandwiched in the NPNPN-GaN structure is completely depleted due to the buil...
