Meeting the Challenges of Power Conversion in E-Bikes
By Maurizio Di Paolo Emilio
In the transportation sector, electric motorbikes (e-bikes) are quickly developing and creating market demand. Electric motors provide the propulsion for these two-wheeled vehicles, eliminating the demand for internal-combustion engines (ICE) that emit greenhouse gases. Zero tailpipe emissions are another way in which electric motorcycles help the environment. Electric motorcycles are an important part of the solution to pollution and climate change as the world seeks alternatives to fossil fuels.
One of the most innovative e-bike manufacturers is Lightning Motorcycles (Lightning), a company that produces advanced, high-performing electric motorcycles. In this article, CEO and co-founder Richard Hatfield explains how and why the company was founded, focusing on the challenges that power electronics engineers face when designing these types of vehicles.
Optical Fiber Probes Boost WBG Power Electronics Development
By Stefano Lovati
Wide-bandgap (WBG) power devices, such as gallium nitride and silicon carbide, can switch at high voltages in a few nanoseconds. Due to the high dV/dt, WBG power devices produce waveforms containing high-frequency harmonics, thus posing unique challenges to designers when accurate measurements must be performed.
Micsig Technology, a company that specializes in manufacturing signal test and measurement instruments, has developed a series of optical fiber-isolated scope probes, called SigOFIT, that allow the performance of measurements on devices operating at voltages up to 60 kV and frequencies up to 1 GHz.
Renewable Energy Transition Trends
By Sonu Daryanani
Efforts to combat climate change have focused on both the supply and usage of energy. Many countries have net-zero carbon emissions goals for the future and the generation of energy through renewable means such as wind, solar and hydro is a key part of the solution. In this article, we will summarize findings from the Reuters Events Energy Transition Insights Report, November 2023. This report identifies key investment and strategy trends driving the energy transition.
Cutting-edge Isolation Solutions Accelerate Advancements in EV Charging
By Stefano Lovati
The rapid growth of electric vehicles (EVs) has become a transformative force as the world moves swiftly toward a greener future. Isolation solutions play a key role in this changing environment, enabling EV charging technology to operate safely and efficiently. Broadcom’s cutting-edge isolation products lead the pack, offering advanced solutions for the electric mobility ecosystem.
At Fortronic 2023, held in Italy on November 16-17, Dr. Saeed Safari, Principal Field Applications Engineer for Broadcom‘s industrial products, delivered a talk titled “Accelerating EV Charging Innovation with Broadcom Isolation Products: Overcoming Design Challenges and Ensuring Safety.” This article focuses on that presentation.

GaN Power Devices: Challenges and Improvements
By Sonu Daryanani
Gallium nitride power devices have the potential to replace legacy silicon power devices in many power-conversion applications. The much-improved conduction and switching figures of merit (FOMs) with GaN lead to improved efficiencies, higher power densities and the possibility to operate at much higher switching frequencies, leading to system-level improvements in cost and performance. In this article, we will summarize some recent developments in GaN discussed at the IEEE Workshop on Wide Bandgap Power Devices and Applications (WiPDA) held Dec. 4–6, 2023.
Nexperia Reveals Breakthroughs in Wide-Bandgap Tech
By Maurizio Di Paolo Emilio
During an interview with Power Electronics News, Nexperia’s Giuliano Cassataro, GaN marketing and commercial director; Katrin Feurle, senior director and head of product group SiC; and Sebastian Fahlbusch, manager of the power Product Application Competence Center, noted the critical need for resilient switching solutions with superior thermal efficiency in industrial and renewable-energy equipment design. They discussed the soaring market demand for high-performance SiC MOSFETs, especially in electric vehicles and solar energy applications. Consequently, Nexperia introduced these new solutions to cater to these specific requirements.
Innoscience Announces Low-Voltage HEMTs in FCQFN package
By Maurizio Di Paolo Emilio
Innoscience Technology has introduced a new line of discrete HEMTs operating at low voltages and packaged in FCQFN. The ‘flip chip’ configuration, which is rated at 40 V, 100 V, and 150 V, simplifies assembly for engineers. There are FCQFN devices rated at 40 V and measuring 4.3 mΩ in on-resistance (with a 3×4 mm chip dimension). RDS(on) values of 2.8 mΩ (3×5 mm) and 1.8 mΩ (4×6 mm) are provided for 100 V HEMTs, whereas the 150 V-rated components measuring 4×6 mm have RDS(on) values of 3.9 mΩ and 7 mΩ, respectively.
Littelfuse Announces 800 V N-Channel D-Mode MOSFET in Modified SOT-223-2L Package
By Maurizio Di Paolo Emilio
Littelfuse has introduced a new 150 mA, 800 V, 45 Ohm, Small Power N-Channel Depletion Mode MOSFET CPC3981Z. In contrast to the conventional SOT-223 packaging, the SOT-223-2L package of this novel product exhibits the absence of the middle pin. This causes the distance between the drain and gate pins to increase from 1.386 millimeters to over 4 millimeters. In higher voltage applications, such as power factor correction (PFC) startup circuits or switch mode power supplies (SMPS), the extended creepage distance is advantageous because it eliminates the necessity for expensive conformal coating or potting, which is undesirable for designers.
