Sumida introduces DC common-mode chokes rated up to 16 A for automotive power electronics

Sumida has introduced the CNFC6D33 and CNFC11D57, a pair of surface-mount DC common-mode chokes that suppress electromagnetic interference (EMI) on DC power lines. The company lists traction inverters, onboard chargers, automotive powertrain systems and automotive HVAC, including electric compressors and PTC heaters, among the applications, alongside industrial and consumer electronics.

The smaller CNFC6D33 measures 7.2 × 6.2 × 3.5 mm. Sumida's product listing rates its versions at 1.5 A and 4 A and gives minimum common-mode impedance at 100 MHz of 500 Ω to 1,970 Ω. Typical impedance reaches 2,500 Ω. DC resistance (DCR) is as low as 15 mΩ maximum.

The CNFC11D57 measures 12.3 × 11.3 × 6.0 mm and comes in three impedance configurations spanning 240 Ω to 1,000 Ω minimum common-mode impedance at 100 MHz. The listing rates its versions at 10 A and 16 A, and DCR is as low as 3 mΩ maximum.

Both parts operate from -40° C to +150° C, including self-heating. Sumida's product announcement also lists an 80 V Hi-Pot test voltage.

A common-mode choke's windings impede noise currents that flow in the same direction on both conductors of a line. The DC supply current flows out on one conductor and back on the other, so its magnetic fields cancel in the core and it sees little more than the windings' DC resistance.

Sumida says both parts are RoHS-listed, have provisional AEC-Q200 compliance and are available through its global distribution network. Custom windings are offered for OEM applications. The company's August product announcement had described the chokes as in pilot production.

"The increasing use of power electronics in vehicles has created new sources of high-frequency electrical noise," said Carl G. LeJambre III, Sumida's Vice President of Sales. "Switching converters, inverters, and onboard chargers can generate unwanted common-mode currents that can interfere with other electronic systems if not adequately controlled."

BTC Power supports Summit Charging’s US expansion

Summit Charging is a “full-service EV charging station developer and operator” that was founded in 2026. The company currently holds NEVI grant awards for eight sites in Washington DC, Texas and California, representing 40 DC fast chargers and 56 charging ports, and is simultaneously developing four self-funded sites in California, and planning five additional sites in New York and Pennsylvania.

EV charging system manufacturer BTC Power has announced its role as a key technology partner with Summit Charging. The two companies have worked together on the technical specifications, Build America, Buy America (BABA) documentation, and site economics behind Summit’s expanding charging network.

Each Summit Charging location is planned to feature at least eight DC fast charging ports supporting both CCS and NACS connectors, along with restrooms and other customer amenities.

BTC Power says its support has helped Summit build stronger business cases for its NEVI applications. BTC Power’s All-In-One DC fast charging platform (available in 180 kW, 240 kW and 320 kW configurations) allows Summit to match charger output to the specific power requirements, traffic patterns and economics of each location. The companies are incorporating Battery Energy Storage Systems (BESS) into site designs to help manage peak power demand and reduce demand-charge exposure.

“Summit Charging is demonstrating what is possible when you combine the right locations with the right charging technology and business model,” said Seung June Oh, Chief Revenue Officer at BTC Power. “They are identifying locations where people already park, shop, work and travel, and developing those locations into public EV charging destinations. We have been developing and deploying public EV charging technology in the US since 2012, and we understand the equipment, site requirements and operating challenges that come with building a reliable charging network.”

Rather than evaluating sites solely by traditional gas station or travel center criteria, Summit assesses each potential location individually, weighing parking, traffic, accessibility, electrical capacity, nearby competition, customer demographics and utility infrastructure before selecting equipment and configuration.

“BTC Power is more than a charger supplier to us. They understand what it takes to turn a location into a viable charging station—from equipment selection and technical requirements to the economics of the project,” said Bruce Lee, founder and President, Summit Charging. “Our experience shows that EV charging can be built in many different types of locations. If a business has the right parking, traffic, and customer demand, there may be an opportunity to add EV charging and create a new revenue stream. Having a technology partner with the experience and product range of BTC Power gives us the flexibility to develop each site based on what that location actually needs.”

Versinetic’s CongaEEL and MinnoRay boards let two AC charger sockets share one controller

EV charger design consultancy Versinetic is launching two charge controller boards for manufacturers of AC chargers. CongaEEL is a power controller board and MinnoRay is a communications and controller board. Two CongaEEL boards can pair with a single controller to build a dual-socket charger, so each socket doesn’t need its own controller.

CongaEEL is intended for public and commercial AC charging. It puts the three-phase mains contactor, an onboard residual direct current detecting device (RDC-DD), current measurement and the ISO 15118 interface on a single board, which Versinetic describes as IEC 61851 compliant. The board stacks with either MinnoRay or MantaRay, the company’s other controller board.

MinnoRay is a compact board designed for cost-sensitive applications. It combines 10/100 Ethernet, an LTE Cat 1 bis modem, Wi-Fi and Bluetooth, and the company says it is OCPP 1.6 compliant. MinnoRay handles communications, while the CongaEEL board it pairs with handles power and safety functions, including the ISO 15118 interface for Plug and Charge.

A manufacturer can use the two boards to build a single- or dual-socket, three-phase AC charger from fewer separate components. According to Versinetic, that cuts the assembly, wiring and compliance testing a charger design would otherwise need to complete from scratch.

MinnoRay is available directly from Versinetic or under license for high-volume manufacturers that build it into their own charger designs.

“CongaEEL and MinnoRay let a manufacturer start from two boards that are already engineered to work together, so the integration work is done before the design even reaches the bench,” said Dunstan Power, Versinetic’s Managing Director.

“They want a connected, compliant charger without carrying the cost of features they don’t need. MinnoRay gives them that option alongside MantaRay, so the choice depends on the build, rather than what we happen to offer,” said Power.

Amazon begins rollout of 50 Mercedes-Benz eActros 600 electric trucks in Germany

Amazon has taken delivery of 27 Mercedes-Benz eActros 600 battery-electric trucks in Germany, the first part of a total order of 50 units that will be delivered by the end of 2026.

In early 2025, Amazon and Mercedes-Benz Trucks signed a contract for more than 200 eActros trucks. In the UK, where the majority of the fleet is being deployed, deliveries began in late 2025.

In total, Amazon is investing more than a billion euros to electrify its transportation network in Europe, including more than 400 million euros dedicated to operations in Germany. The transition includes the installation of hundreds of heavy-duty EV chargers at the company’s European facilities.

Amazon is deploying the eActros 600 on middle-mile routes, transporting goods between fulfillment centers and urban areas.

The eActros 600 has three LFP battery packs, each with 207 kWh of capacity. The total capacity of 621 kWh supports a range of up to 560 kilometers in long-haul transport with a gross train weight of 40 tons. With a standard semitrailer in the EU, the eActros 600 has a payload of around 22 tons.

Mercedes-Benz Trucks recently added additional variants to the eActros 600 lineup. Customers can choose between two cab variants, two or three battery packs, numerous wheelbases, and new axle configurations. In total, the second-generation of the eActros offers over 40 variants of the base vehicle.

“The eActros 600 was developed for demanding long-haul transport,” said Stina Fagerman, Mercedes-Benz Trucks’ European President. “The fact that Amazon relies on our vehicles underscores the confidence in our technology and also shows that the electrification of heavy-duty transport is increasingly becoming reality.”

“The handover of these vehicles is a milestone for the electrification of our transportation network,” said Andreas Marschner, VP of Worldwide Sustainable Operations at Amazon. “Electric solutions have already been widely used for some time in last-mile package delivery to customers. With the high-performance electric trucks from Mercedes-Benz Trucks, we can now make even longer transport routes between fulfillment centers and urban areas more sustainable.”

Hirect’s in-house 6,000 hp electric locomotive propulsion system completes acceptance testing

Indian power electronics manufacturer Hirect has completed the acceptance regime for its 6,000 hp (4,475 kW) electric locomotive propulsion system, which hauled loaded freight in a WAG-9 locomotive under what the company describes as severe duty cycles and a demanding thermal operating environment. Hirect designed, engineered and manufactured the system in-house, including its liquid-cooled IGBT traction inverters and converters and its own control software. The qualification opens one of the world’s largest locomotive markets to its complete propulsion package, Hirect says, and establishes a modular subsystem platform for new-build, retrofit and hybrid locomotive programs internationally.

The company has also secured a development order from Indian Railways’ Modern Coach Factory for complete propulsion systems for four Mainline Electric Multiple Unit (MEMU) trainsets. The 24-month program covers traction transformers, traction motors and the fully integrated propulsion system, including the Train Control and Management System (TCMS). Hirect describes it as its first development order for a complete trainset propulsion system. A MEMU carries its traction equipment distributed beneath the cars of the trainset rather than concentrated in a locomotive.

Hirect’s rail portfolio also includes traction transformers, IGBT converters, auxiliary power supplies, SiC battery chargers, traction motors and HVAC systems.

That equipment, the company says, supports the transition from diesel traction to hybrid, electric and alternative-energy traction, including hydrogen.

“Powering Indian Railways locomotives with a propulsion system designed and produced entirely in-house, and delivering the complete power and control systems for modern trainsets, demonstrates the strength of our R&D and our ability to take responsibility for the whole system—from the dielectric coating on our copper wire to the control software,” said Suramya Nevatia, Hirect’s Chairman and Managing Director.
