Toyota, Nissan, and Samsung have begun pilot production of all-solid-state batteries, reports TrendForce. Production volumes could reach GWh levels by 2027. Solid-state batteries offer promising improvements in safety and energy density, but they continue to face significant challenges, including high production costs, complex manufacturing processes, and a lack of a mature supply chain. TrendForce projects that, by 2030, if the ...

Renesas is aiming at Intel’s Core Ultra 200V series of processors with a pair of power ICs. RAA225019 is a six-phase buck converter, designed to work with IMVP9.2 Lunar Lake processors. Integrated within is the switching controller, power mosfets and current-sensing. “Six phases can be distributed across three outputs – two SVID rails and one auxiliary rail,” said Renesas. “SVID1 ...

Vishay has stretched an SO-6 package to accommodate 1kV operation from opto-based mosfet and IGBT gate drivers. The body is ~7mm from end to end and creepage is 8mm. Clearance is 7mm for the ‘option 9’ package which has conventionally bent legs, or 8mm for the ‘option 8’ package which has widely-splayed legs (see image). Peak working voltage is 1.14kV ...

Infineon is looking towards 1,500V dc links with a 2kV 80A silicon carbide Schottky diode. IDYH80G200C5 is the 80A 2,000V part, which comes packaged in four-lead TO-247PLUS-4-HCC, with 14mm creepage and 5.4mm clearance. Only two of the leads are used – the two adjacent to the creepage slot. The cathode is connected to the separated pin as well as the ...

ProTek Devices has introduced a pair of 15kW transient voltage suppressors for 28V aircraft circuits. “The devices meet compliance for MIL-STD-704 and MIL-STD-19500, in addition to being RTCA DO-160G compliant,” according to the company. They are called: PAL704-P15K36 is 50 x 19 x 12mm 30g with flat terminals PAL704-P15K36T 63 x 23 x 17mm x 48g with turret terminals Both ...

Vox Power Ltd has announce the EIRE300 series of 300W open-frame ac-dc power supplies for medical and IT equipment use, that measure 4 x 2 x 1inch. 300W is with forced air and only 200W (115Vac) is available continuously if only convection cooling is available – with ambient temperature caveats. Up to 375W can be delivered for 1s. Different models ...

Omron has launched a single-pole PCB relay that can break 150A and handle 800V. G7EB-A1-E2 has a 36.7 x 50mm footprint and is 40.2mm tall. Circuit breaking life is 100 operations at 150A 480Vac or 30 operations at 150A 800Vac. “The device is ideal for providing safe system operations with an emergency stop function, and eliminates the need for other ...

The winner of the latest UK-APAC Tech Growth programme, Heronic Technologies, will collaborate with Rohm Semiconductor to explore how Rohm can develop its own power semiconductor materials for emerging technologies. Heronic specialises in AI accelerator architectures. Its proprietary technology customises chips for optimum efficiency and performance “beyond the capabilities of generic architectures” for specific AI applications. The Tech Growth programme ...

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 ...
