Bel Fuse has announced 4kW liquid-cooled dc-dc converter for low voltage accessories in hybrid and electric vehicles. Called 350DNG40-12-8, it can deliver between 10 and 15Vdc from 240 to 450Vdc at up to 93% efficiency with full galvanic isolation between input and output. It features a CAN bus interface (output trimming is via CAN) and IP67 or IP6k9k environmental ratings, ...
Maria is senior vice-president at Advanced Energy and responsible for a team developing the company’s power products. She talks to Caroline Hayes about her passion for power design. For Maria Cortez, the main design conundrum is the “tension between the ever-increasing demands for higher power versus a need to conserve energy”. “For example, artificial intelligence has been driving higher levels ...
XP Power has released two baseplate-cooled dc-dc converter series with 14 to 160Vdc (12:1) inputs. Nominally running from 72V rails, they are rated at 150W (RDF150 series) or 200W (RDF200 series) and designed for use in railway, renewable energy and industrial applications. “The voltages available in railway applications vary globally, often requiring different power designs to suit each geography,” according ...
Leclanché is using niobium-based XNO-branded anode material from Echion Technologies in a lithium-ion cell, aiming it at heavy duty e-mobility, rail and marine use. “We are absolutely delighted to announce the launch of the world’s first commercial XNO Li-ion cell,” said Leclanché CEO Pierre Blanc. “XNO is set to displace the use of LTO within our product line and it ...
Aiming at vehicle traction, Infineon has put a pair of 3,300V 1,000A 1.9 mΩ silicon carbide trench mosfets into its 100 x 140 x 40mm ‘XHP 2’ module housing, calling the module FF2000UXTR33T2M1. This package is rated for 6kV testing, and achieves 2.6kV partial discharge extinction. Creepage is 40mm terminal to baseplate and 34mm between terminals. Clearance is 31 and ...
Hungarian state-owned energy company MVM Balance has ordered a 4.35MWh 750kW sodium-sulphur battery from NGK for a grid storage demonstration project. Due to be operational in May 2025, it will consist of three shipping-container-sized units, installed at a power station in Litér, Veszprém. “The project will verify the use of grid storage batteries for storing energy during times of surplus ...
Onsemi has announced a 112 x 62mm power module for flying capacitor boost converters up to 1kV. It combines 1kV silicon IGBTs and 1.2kV silicon carbide diodes in the company’s F5BP package. Called NXH500B100H7F5SHG, it can handle continuous collector currents up to 210A (630A pulsed) (Tj = 175°C). Abs max power dissipation is 305W. To reducing stray inductance and thermal ...
Bourns has added six shunt resistor types its Riedon range, that it acquired in April last year when it bought Riedon Inc. Construction is with brass end-caps holding Manganin resistance elements. The latter has a temperature coefficient ~±15ppm/°C. Kelvin contacts are provided for the voltage output. Panel-mount RS resistors have values from 41.7μΩ to 20mΩ (±0.25%). There are sub-versions here: ...
It seems to be Ideal Diode Week at Electronics Weekly (here and here) as Diodes is also promoting one, this time an ideal diode that can cope with ±65V on its input and drops only 20mV when conducting. The automotive-compliant AP74700Q operates down to 3.2V (or 3.9V at start-up) to allow for cold cranking of a vehicle engine. Inside, a ...
Power factor correction with CCM (continuous conduction mode) boost converters is where ITG Electronics is aiming its latest choke family. Specifically, the series is for converters operating at between 100 and 200kHz, and up to 3.3kW. There are four parts, from 90 to 285uH, all with a 43 x 35mm footprint and standing 38mm above the PCB. They can operate ...
