In the past year, we will find an obvious phenomenon: more and more game advertisements, even embarked on television media, walked into variety shows, and became a popular phrase for many people to meet. We can say that the game in this era has played an increasingly important role, and the game industry has ushered in an unprecedented culmination. If you say the game, it is natural to say that different types of games also have different status. It is generally accepted that mobile games have been blown out in the past two years, and that they are not as good as traditional endgame and PC games. Of course, this is in line with the current state of the Internet development. According to the data of the “2017 China Game Industry Development Reportâ€, in 2017, China Mobile’s game users were approximately 460 million, an increase of 9.0% year-on-year; the number of client game users was approximately 150 million, which was basically the same as 2016; web game users were approximately 2.4. Billion, a year-on-year decrease of 2.0%. In terms of the overall situation, there has been a noticeable increase in online game users. The same is true of the gaming industry turnover in the past year: In 2017, the overall operating revenue of China's game industry was approximately RMB218.96 billion, a year-on-year increase of 23.1%. These figures are sufficient to prove that the Chinese game market in 2017 is in a fast-paced growth trend. The author believes that in 2018 the game market will continue to grow. Because, from the point of view of the development of the game industry, the game ecology has been in the process of continuous formation and improvement in the past year, and lack of standardization (such as piracy). In the future game industry, in addition to the industrial standardization and ecological improvement, the maturity of the technology will also be an important cornerstone leading the sustained and healthy development of the game industry. Take VR games as an example. According to the “2017 China Game Industry Development Reportâ€, VR game revenue was RMB 400 million, a year-on-year increase of 28.2%. This data is second only to the growth rate of mobile games, which is much higher than the growth of web games and mobile games. VR experience area If we analyze the user form, we will find that the number of VR game users is not large (about 40 million), in the range of user growth, mostly through the VR Experience Museum, the number of consumers. In terms of real life, various immersive games and entertainment venues covering VR technology have appeared in all major shopping malls in 2017. For such new products and technologies, people are always willing to try, but due to insufficient technology maturity, the industrial ecology is not perfect enough, there are many bottlenecks, and individuals who purchase VR game devices are still rare. It cannot be denied that if the technology matures quickly, VR games will have a very substantial market. However, in the current game ecology, VR games are still marginalized, with many experiences and difficulties in translation. The reasons are: the immaturity of technology (such as the speed increase from 2D to 3D, perspective issues, depth of field processing), but also the limited resources of the game, the quality of resources levels are not uniform. The future of the game market will continue to be hot, it will also be the stage of rapid growth of VR, will inevitably usher in a new round of victory. With the establishment of industry norms, the game market will be more standardized, and the interests of consumers will be better protected. TO-220 Transistor Outline Package is a type of in-line package often used in high-power transistors and small and medium-sized integrated circuits.
It not only plays the role of mounting, fixing, sealing, protecting the chip and enhancing the electrothermal performance, but also connects to the pins of the package shell with wires through the contacts on the chip, and these pins pass through the wires on the printed circuit board. Connect with other devices to realize the connection between the internal chip and the external circuit.Because the chip must be isolated from the outside world to prevent impurities in the air from corroding the chip circuit and causing electrical performance degradation. On the other hand, the packaged chip is also easier to install and transport.
TO-220 package is a kind of in-line package that is often used for fast recovery diodes. TO-220AC represents a single tube with only two pins and only one chip inside.
The diodes are packaged in TO-220AC and can be used in switch mode power supplies (SMPS), power factor correction (PFC), engine drives, photovoltaic inverters, uninterruptible power supplies, wind engines, train traction systems, electric vehicles and other fields.
