Article: Wireless Charging Keeps Drones Hovering in the Sky

2020-07-23T11:54:39-05:00July 23rd, 2020|Categories: Article, Featured, GaN Systems|

The demand for more efficient and flexible recharging solutions is constantly increasing, especially aiming at leading the next generation of robotic systems towards greater autonomy.There are large companies with big plans to offer services based on drone fleets, and they are all eager to get beyond a significant operating challenge: the flight time of commercial

Article: It’s Time to Amp Up Bus Electrification

2020-07-08T17:31:34-05:00July 8th, 2020|Categories: Article, Featured, Wolfspeed|

If the goal of moving to electric vehicles (EVs) is to reduce harm to the environment, then getting people out of individual cars and on electrified public transit should be a premier destination as well. While they may not look as sleek as the latest Tesla, electric buses are going places, too, despite similar range

Article: Reduce Size and Increase Efficiency with GaN-based LLC Solution

2020-07-08T17:16:49-05:00July 8th, 2020|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 frequency

GaN Enables Efficient, Cost-effective 800V EV Traction Inverters

2020-07-01T17:03:35-05:00July 1st, 2020|Categories: Article, Featured, GaN Systems|

For EVs, the semiconductors used in traction inverters have a significant impact on efficiency, power density, and cooling requirements. The three-phase AC motors used in today’s EVs run at voltages up to 1,000V and switching frequencies up to 20 kHz. This is very close to the operational limits of the silicon-based metal-oxide semiconductor field-effect

Step-by-Step Process for Selecting an EMI Filter

2020-07-01T16:56:55-05:00July 1st, 2020|Categories: Article, AstrodyneTDI, Featured|

Selecting an appropriate EMI filter is critical to achieving optimum size, performance, and cost. Different types of EMI filters provide different levels of suppression and have different characteristics. What works for one system might not work well in another. For this reason, it is essential to understand the considerations when selecting an EMI filter.

Q&A: Wide Bandgap Semiconductors Poised to Make a Splash

2020-07-01T16:48:48-05:00July 1st, 2020|Categories: Article, Featured, GaN Systems|

With silicon nearing its physical limits, electronics manufacturers are turning to non-traditional semiconducting materials, notably wide-bandgap (WBG) semiconductors. Some are adopting these technologies to hit cost and performance targets that otherwise can’t be reached, and while others seek to differentiate their products from their competitors’.

How 650V SiC MOSFETs Reinvigorate Battery Charger Power Designs

2020-06-23T16:44:38-05:00June 23rd, 2020|Categories: Article, Featured, Wolfspeed|

By switching to SiC MOSFETs, power system designers can significantly boost power density, lower switching losses, and improve thermal management in OBCs for electric vehicles. Power systems in electric vehicles (EVs), on-board and off-board battery chargers, and other energy storage systems are demanding greater energy efficiency to pack more power into... Read More!

iCoupler Technology Benefits GaN Transistors in AC/DC Designs

2020-06-23T16:38:22-05:00June 23rd, 2020|Categories: Analog Devices, Article, Featured|

Highly efficient ac/dc power supplies are key to the evolution of the telecom and datacom infrastructure, as power consumption grows rapidly due to hyperscale data centers, enterprise servers, or telecom switching stations. However, the power electronics industry has reached the theoretical limit of silicon MOSFETs. Meanwhile, recent gallium nitride (GaN) transistors have emerged as
