“Here’s to the crazy ones, the misfits, the rebels, the troublemakers, the round pegs in the square holes … the ones who see things differently — they’re not fond of rules, and they have no respect for the status quo. …
You can quote them, disagree with them, glorify or vilify them, but the only thing you can’t do is ignore them because they change things. …
They push the human race forward, and while some may see them as the crazy ones, we see genius, because the people who are crazy enough to think that they can change the world, are the ones who do.” – Apple Inc. (1997 Think Different campaign)

德州仪器:简化HEV 48V系统的隔离CAN、电源接口
近日,德州仪器的Anant Kamath发表了《简化HEV 48V系统的隔离CAN、电源接口》的技术文章,全文如下:
48V汽车应用中对隔离的需求持续增长。这是一种紧凑、高效、稳健、低噪声的方法,可通过CAN接口隔离48V系统。
为今天的汽车设计是一种平衡行为。在满足日益严格的排放标准和为越来越多的车载系统和小工具提供动力之间,需为当今的车辆提供高功率,以获得高效率。
为实现效率和功率的融合,工程师更加依赖于将48V电力运行与传统燃气发动机相结合的系统,如混合动力电动汽车(HEV)。这种方法可确保车辆满足严格的二氧化碳(CO2)排放标准,同时还可改进性能和驱动质量。
虽然关于双电池汽车系统本身已有很多说法,但本文关注的是这些组合式12和48V系统中的一个关键且有时被忽视的组件:电流隔离。电流隔离用于抵抗接地噪声,并在与其连接的48 V系统中接地断开或故障时保护12V系统。
本文将讨论48V汽车应用中隔离的需求,并描述一种紧凑、高效、稳健和低噪声的方法,通过控制区域网络(CAN)接口隔离48V系统。
