Transphorm’s latest GaN transistor passes automotive qualification
Semiconductor provider Transphorm has announced that its third-generation high-voltage gallium nitride (GaN) field-effect transistor (FET) has passed AEC-Q101 stress tests for automotive-grade discrete semiconductors. The transistor targets EV applications including on-board chargers, DC-DC converters, and DC-AC inverter systems. Transphorm’s new FET, the TP65H035WSQA, performed at 175° C during AEC-Q101 qualification testing, which the company says… Read more »
Johnson Controls and Toshiba partner to pair Li-ion and lead-acid in dual-battery systems
Johnson Controls and Toshiba have partnered to develop low-voltage lithium-ion batteries, which they’ll pair with existing lead-acid batteries for dual-battery systems. Paired systems require fewer powertrain alterations than other electrified powertrains, and achieve up to eight percent better fuel efficiency than conventional systems, according to Johnson Controls. Global information provider IHS Markit forecasts that dual-battery… Read more »
