【Design and Development of High Efficiency 150 kW Very Compact PLA Core Electromagnetic Coupler for Highly Resonant Power Transfer Technology】

Article by Fatima Zahra Boudara, et al., from Univ Pau & Pays Adour/E2s Uppa (France), etc.

In toroidal coupler, the winding occupies the full periphery of the core, resulting in reduced leakage inductance and stray electromagnetic field. It is widely used in low power applications, but is still not very available in high power ones and less studied compared to the conventional transformer. This work investigates the possibility of replacing a conventional transformer by a galvanically isolated PLA core toroidal electromagnetic coupler in order to address the main challenges of smart grid technology using the inductive transmission method. And an ultra-compact PLA core electromagnetic coupler was presented, designed, simulated, built and tested.

【博学之士】从19世纪中期开始，科学领域涌现出了大量的专家，然而像艾伦·图灵（Alan Tuing)和莱纳斯·鲍林(Linus Pauling)这样的博学之士仍然起着决定性作用。Peter Burke在思维延展的历史中描述了自列奥纳多·达·芬奇(Leonardo da Vinci)以来的500年里的“500位西方博学家”。他讨论了他们的好奇心、专注力、记忆力、速度、想象力、不安、勤奋和对浪费时间的恐惧。但他忽略了有博学倾向的专家，如阿尔伯特•爱因斯坦（Albert Einstein）、弗洛伦斯•南丁格尔（Florence Nightingale）和罗纳德•罗斯(Ronald Ross)。https://t.cn/A6biwqe3

【集装箱之外】全球化的历史让人想起经济学家Marc Levinson在2006年出版的《集装箱改变世界》（The Box）一书。始于上世纪80年代的集装箱是 “第三次全球化”的关键:产品在工资不高的地方制造，再运到设计它们的发达经济体。在今天的“第四次全球化”中，科研、工程和设计正在流动，制造可以在任何地方进行。这个过程主要涉及的是软件一类的创意，而不是集装箱里的“东西”。但如何才能从政治角度加以调控它呢?https://t.cn/A6biwqe3
