Thermal management considerations for board-mounted dc/dc converters

January 13, 2021 By Jeff Shepard

System-level thermal design is equally important to the electrical specifications of board-mounted dc/dc converters. And the growing use of variations on a distributed power architecture (DPA) increases the complexity of thermal design. A single multiple-output ac/dc power supply is used to power the various loads in a conventional power architecture. The use of a centralized […]

SiPs combine two GaN HEMTs, high-voltage gate drivers

January 8, 2021 By Redding Traiger

Building upon the advantages of STMicroelectronics’ MasterGaN platform, MasterGaN2 is the first in the new family to contain two asymmetric gallium-nitride (GaN) transistors, delivering an integrated GaN solution suited to soft-switching and active-rectification converter topologies. The 650V normally-off GaN transistors have on-resistance (RDS(on)) of 150mΩ and 225mΩ. Each is combined with an optimized gate driver, making GaN […]

Next-gen BMS goes wireless, with proprietary protocol and functional safety compliance

January 7, 2021 By Aimee Kalnoskas

Because today’s battery management systems (BMS) are wired, the common source of cable failures – wire harnesses and connectors – becomes a warranty and functional safety issue. With the launch of a wireless BMS that features the first independently assessed functional safety concept, Texas Instruments hopes to revolutionize electric vehicle (EV) BMS. By removing the […]
