Infineon has expanded its silicon carbide wafer agreement with Wolfspeed. The multi-year arrangement supports Infineon’s transition towards 200mm manufacturing, building on an established 150mm substrate relationship without disclosing volumes or commercial terms.
-
Sungrow has selected onsemi power modules for its PowerTitan platform. EliteSiC hybrid devices are integrated into a three-level inverter architecture, with reported performance gains at the conversion stage.
-
Microchip has launched a radiation-tolerant converter for spacecraft electronic systems. The POL-05-20S-T uses GaN devices to supply up to 20A with published radiation and temperature characteristics.
-
Delta has announced integrated motors and pumps for industrial cooling. The EC designs combine compact construction, onboard control and options for high-voltage DC distribution in data centres.
-
Navitas has unveiled a 24kW board for AI power distribution. The design converts 800V DC directly to 12V, targeting 97% efficiency at full load.
-
Polar will manufacture enhancement-mode GaN devices using technology from imec. The US foundry has agreed a process transfer covering initial 40V-to-650V devices, while IC-Link will provide a path from design work towards commercial manufacturing.
-
AVL has integrated VisIC gallium nitride modules into a vehicle. The demonstrator extends earlier dynamometer work into a complete electric drivetrain, although published peak efficiency results still come from bench tests.
-
Power Integrations and Ideal Power are developing semiconductor circuit breakers. Their working 800V DC prototype combines a 1700V InnoMux-2 power conversion device with B-TRAN switching, while a reference design remains in development.
-
Texas Instruments has introduced three chips for AI infrastructure electronics. They cover fast power-rail event capture, 800V DC insertion protection and low-jitter timing for high-speed links.
-
HARTING has joined NVIDIA’s MGX ecosystem with new power assemblies. The 480V AC connection targets Vera Rubin equipment, while an 800V DC design addresses a later power architecture.
