GaN is Driving Power Semiconductors

2019-10-02T16:52:19-05:00October 2nd, 2019|Categories: Article, Featured, GaN Systems|

Power semiconductor devices with gallium nitride (GaN) and silicon carbide (SiC) are gradually replacing their silicon-based counterparts, largely because using GaN or SiC power transistors can lead to more straightforward and efficient energy storage solutions. The combined GaN and SiC market is projected to be valued at over US$3 billion by 2025 and will be

Using MOSFET Controllers to Drive GaN E-HEMTs

Before gallium nitride (GaN), the silicon (Si) MOSFET was the standard for power in adapter applications for decades. As a result, many of the existing controllers in the marketplace, including power factor correction (PFC) and DC-DC controllers, have already integrated silicon drivers into the controller chip. These controllers have proven to be a cost-effective and

Benchmarking System Architectures and Topologies for DC-to-DC Converters, the Heart of Off-Board Chargers

Electrical vehicles (EVs) pose a host of questions, challenges and problems for people seeking to put this breed of car on the road. OEMs’ engineers have one set of issues to tackle, and infrastructure planners quite another, while policymakers are busy assembling the puzzle pieces of renewable energy, EVs and the smart grid. If

Lasers for Lidar: Monolithic multichannel laser moves automotive lidar toward practical use

2019-08-19T10:40:07-05:00August 19th, 2019|Categories: Article, Featured, GaN Systems|

A four-channel laser and ultrafast driver delivers more than 480 W peak power in 2 ns pulses. The driving force behind nearly all of today’s autonomous vehicles is the extraordinary, high-powered lasers driving lidar (light detection and ranging) systems. Lidar, featuring infrared lasers, navigates autonomous vehicles by creating a real-time, 3D image of the

This article examines SiC MOSFETs as a viable option for meeting the rising demand for faster switching and greater efficiency in 1500 V solar applications. It looks at their benefits – SiC MOSFETs enable deeper integration and greater power density – and their drawbacks in terms of switching performance. The intrinsic properties of the

Reduce Size and Increase Efficiency with GaN-based LLC Solution

2019-07-31T16:51:31-05:00February 17th, 2019|Categories: Article, Featured, GaN Systems|

GaN High Electron Mobility Transistors (GaN HEMT) have lower driving loss and shorter deadtime circuit benefits due to significantly reduced gate charge (Qg) and output capacitance (Coss) compared to Silicon MOSFETS. Therefore, GaN HEMTs show significant advantages over Silicon MOSFETs in high-frequency soft-switching resonant topologies such as an LLC resonant converter. With increased switching
