At present, the world faces four major problems to be solved: globalization, urbanization, aging and low carbonization. These four major problems have brought severe challenges to the electronics industry, but also brought huge opportunities. First, the trend in the entire semiconductor industry is to reduce energy consumption with ultra-low power consumption. Secondly, the social problems brought about by aging include higher demand for the medical industry, and at the same time, it brings more challenges to medical electronics. The new challenges presented by the development of medical electronics to the semiconductor industry are mainly focused on front-end high-resolution sensors and high-precision analog-to-digital converters. Once again, the process of globalization has brought everyone closer. And such changes are largely dependent on the development of communication technologies. Modern communication can be said to be far-reaching, and the development of electronic communication technology is obvious to the contribution of saving the earth's energy. Finally, the urbanization process has brought amazing changes to urban development, and at the same time, it has brought severe challenges to the urban transportation system. The electronics industry plays an irreplaceable role in the control of urban transportation systems, and these aspects will become the growth point for the electronics market.

Energy will be another hot spot, and energy conservation and emission reduction has been one of the main topics in recent years. From the perspective of the development of green clean energy, whether it is wind or solar energy, it has developed rapidly in both Europe and America and China. Driving the growth of the semiconductor and electronics markets is growing detection and control technology. In recent years, China will continue to invest in new energy and smart grid construction. We can see more demand for high-precision analog-to-digital converters and precision operational amplifiers, processors and controllers that support network functions, and long life. Wide temperature range, highly reliable isolation device. In general, the demand for the Chinese electronics market is still huge, and the overall growth trend will moderately slow down.

Simply put, the main market for new energy is the application of new energy in energy systems and power systems. It exists in the four links of power system transmission, transmission, distribution and use, which is also an important part of the smart grid concept. . There are many key problems in the construction of new energy. Among them, new energy power generation technology, new energy grid connection, large capacity energy storage, UHV transmission, demand side management and smart metering technology should be the focus of the industry. key point. For the new energy market, the most important challenges we face will be the requirements of the new standards, the problems faced by the smart grid and the cost pressures, especially the requirements of solar photovoltaic inverters and grid-connected equipment in Europe and the United States, micro-inverter versus cost. Requirements.

For smart grid construction, solar PV inverters will be a major market opportunity, and China has huge business opportunities in using semiconductor technology to greatly improve power transmission and distribution and to develop new renewable energy sources such as wind and solar. China has advantages that many other countries do not have because we have just begun a new page in many areas. China State Grid has announced an investment of 4 trillion yuan for power infrastructure construction. This investment is 100 times that of the rest of the world, and its goal is to build a nationwide smart grid by 2020. This is the most ambitious smart grid project in the world. In addition, according to industry forecasts, China's electricity demand will double by 2020. This growth means that demand for new products will also grow, including smart meters, power station replacements, solar and wind power plants and transmission equipment, and ultra-high voltage transmission lines.

In addition, the new standards in Europe and the United States will require new energy equipment, especially solar photovoltaic inverter equipment, which requires higher conversion efficiency, longer service life, wider practical temperature range and higher grid-connected equipment. EMC requirements. From a safety perspective, both the controller and the inverter require complete isolation. These specific requirements have also spawned and promoted the development of the corresponding industries, especially for some new types of semiconductor devices, for long-life, high-temperature isolation devices, devices that improve current and voltage detection accuracy, and low-cost controllers. There is a big increase.
