Sumida is using the 2024 APEC Power Electronics Conference for the North American introduction of two new series of AEC-Q200 qualified power inductors, the DPQ3535/T150 and DPQ5050/T150. These inductors are magnetically shielded and have a pin-type base for surface mounting on printed circuit boards. High surface area flat-wire windings minimize internal resistance at high frequencies […]
EV Engineering
Vehicle-to-grid is technically feasible, but what’s the reality?
A concept may be elegant and even possible to implement, but the actual benefits are dubious — especially with the stress it gives to users. You’re probably somewhat familiar with the idea of vehicle-to-grid (V2G) automobile energy transfer. It’s been a “hot” topic for the last few years, largely due to the increase in the […]
How can quantum sensors and quantum batteries improve electric vehicle operation?
In the near term, quantum sensors are being developed that can more accurately measure EV battery capacity, assess battery safety, and reduce vehicle weight. In the longer term, quantum batteries have been proposed that could dramatically improve the speed and efficiency of battery charging. The energy remaining in an EV battery has been estimated using…
Half-bridge transformers boast chip-style construction
HTX7045C Series transformers feature a chip-style construction – a significant advancement over traditional core and bobbin designs that not only reduces the size of the component but also streamlines the manufacturing process, resulting in a more cost-effective solution. It offers low interwinding capacitance (as low as 0.7 pF), making it particularly well-suited for use in […]
Power-dense sensors help designers minimize footprint of GaN and SiC devices
Allegro MicroSystems, Inc. announced the launch of its new high-bandwidth current sensors, the ACS37030 and the ACS37032, which enable high-performance power conversion with GaN and SiC technologies in electrified vehicles, clean energy solutions, and data center applications. Current high-power-density GaN and SiC FET charging and power infrastructures demand highspeed, low-loss devices to ensure efficiency and […]
How to use remote sensing for DC programmable power supplies
In this FAQ, you’ll learn how to know if your test application needs sensing and how to properly wire a power supply to a load. Calibrating certain sensing circuits, such as those used in electric vehicles (EVs), is critical to get right. An inaccurate calibration of an automotive battery monitoring circuit could, for example, allow […]
Reed relays now offered in 5kV stand-off, up two 1.5kV switching version
Pickering Electronics has added a 5kV stand-off, up to 1.5kV switching version to its single-in-line Series 104 reed relay family. Previously, to achieve a 5kV stand-off rating, a larger, non-SIP (Single-in-Line-Package) relay was required. Four of the new 104 5D parts can fit the same PCB area that one larger style occupied, even with sufficient […]
How is AI being used to improve electric vehicle efficiency?
Electric vehicles (EVs) are all about reducing carbon emissions. Artificial intelligence (AI) can help. This FAQ looks at a few examples like how AI and machine learning (ML) can be used to make context-aware operational recommendations to EV drivers for extending EV battery lifetime and how AI can work together with wide bandgap semiconductors (WBGs) […]
1200 V SiC power MOSFETs now amiable in half-bridge packages
SemiQ Inc. has expanded its QSiC power modules portfolio with the introduction of a new series of 1200V silicon-carbide (SiC) power MOSFETs in half-bridge packages. Engineered and tested to operate reliably in demanding environments, these new compact, high-performance modules enable high-power-density implementations while minimizing dynamic and static losses. Featuring high breakdown voltage (>1400V), the new […]
Trigger alerts when Li-ion batteries get too hot
TTape from Littelfuse, set of temperature-triggered switches, raises a bit that indicate hot batteries. Li-ion batteries can get hot, which can cause failures or worse in the products they power. Thus, it’s important to monitor their temperature and act before damage occurs. You can monitor temperature with a set of thermocouples, scan them, and write…
