On July 29, 2018, the 17th National College Robot Competition RoboMaster 2018 Masters Finals ended at Shenzhen Bay Sports Center. The last champion of South China University of Technology team successfully defended. This year's RoboMaster has clearly received more attention than last year, thanks to various attempts made by Dajiang during the year, including the production of the reality show "Superpowered Works", the same name animation "Mechanics Master" And the documentary "Mechanic Masters" also includes vigorous publicity in various primary and secondary schools in Shenzhen. In the final game, the two primary school students and their parents behind me can even analyze the strategic advantages of the various robots of South China University of Technology, which shows that this event has a good influence in the student group. Why can a mechanical engineering student participate in a robotic combat game with more and more "fans"? I...

Facebook has invested in virtual reality (VR) and augmented reality (AR) for some time and has become a driving force for technological advancement. Now, the company is looking to attract more users by launching new tools on the Facebook platform, which will make it easier for marketers to create AR ads that engage users on mobile devices.

What restricts power miniaturization?

图片
With the development of power modules, engineers have focused on how to make modules smaller and lighter. In fact, we all understand that we can increase the power density of products by increasing the switching frequency. But why has the module's volume so far not changed so much? What restricts the increase of switching frequency? With the application of switching power supply products under the market, increasingly smaller, lighter, high-efficiency, low-radiation, low-cost and other characteristics are required to satisfy various electronic terminal equipments. In order to meet the current portable electronic terminal equipment, the switching power supply must be made small in size. Due to its light weight, it has become a matter of increasing concern for designers to increase the operating frequency of switching power supplies. However, what are the factors limiting the frequency of switching power supplies? In fact, it mainly includes three aspects: switch tubes, transformer...
