This week 氮化镓系统 (GaN Systems)‘ CEO Jim Witham appeared on the Energy Cast Podcast, a program focused on exciting technology and energy advancements. Listen to it here or on the podcast app of your choice. I’ll admit, I didn’t really know the difference between microprocessor semiconductors (Intel/AMD) and the power semiconductors developed by this week’s…
Smart mobile electronic devices have changed the way that we perceive and interact with the world around us. Electric cars, buses, scooters, and bikes are transforming the face of our urban transportation landscape. Autonomous robots in intelligent factories and aerial drones making deliveries are challenging past preconceptions about the ways that we create and distribute…
本文最初发表于Acuris.com 首席执行官表示，GaN Systems可以寻求子组件装配战略合作伙伴。 总部位于加拿大渥太华的氮化镓能源系统公司GaN Systems可能寻求合作伙伴或资本，以扩大其制造子级组件的能力。 Witham拒绝透露财务数据，但据一份行业报告称，该公司是氮化镓晶体管出货量的市场领导者，整体市场规模为100亿美元。 他说，晶体管已在多个市场中使用，该公司的目标是五种应用：消费性设备充电器，数据中心，可再生能源，工业用电机和电动汽车。

OTTAWA, Ontario, Canada, May 28, 2019 – 氮化镓系统 (GaN Systems), the global leader in GaN (gallium nitride) power semiconductors, is sponsoring the distinguished China Power Supply Society (CPSS) design competition, now underway with a record-breaking 40 engineering teams entering the competition from leading universities throughout China. 氮化镓系统 (GaN Systems) recently participated in the kick-off ceremony at…
This article was originally published on Forbes.com on May 16, 2019 by Jim Witham, 氮化镓系统 (GaN Systems) CEO. We are in the midst of the Fourth Industrial Revolution. The first assembly lines introduced 100 years ago and the computers added 50 years later seem almost primitive as intelligent cyber-physical systems take their place on factory…
氮化镓系统 (GaN Systems) announces an upcoming webinar on Thursday, May 16th at 11:00 AM Eastern Daylight Time titled: The Effect of Dynamic On-State Resistance to System Losses in GaN-based Hard-Switching Applications. GaN power transistors are the building blocks of change for the design of a new generation of smaller, lower cost, more efficient power systems…
