加拿大28精准大小算法 The power module is a new generation of switching power supply products developed by modern electronic technology. The grades are divided into civilian, industrial and military. Mainly used in switching equipment, access equipment, mobile communications, microwave communications and optical communications, routers and other communications and automotive electronics, medical, power, transportation, energy, industrial control, aerospace and many other fields. Due to the short design cycle, high reliability and easy system upgrade, the module power supply has more and more applications. Especially in recent years, due to the rapid development of data services and the continuous promotion of distributed power supply systems, the increase of module power supply has exceeded the primary power supply. With the large use of semiconductor technology, packaging technology and high-frequency soft switches, the module power supply density is getting larger and larger, the conversion efficiency is getting higher and higher, and the application is becoming more and more simple. Domestic enterprises have basically mastered the core technologies, industrial investment has been increasing, and market demand has gradually increased.
In 2011-2015, as China entered the “Twelfth Five-Year” development stage, the economy gradually resumed its steady growth momentum, and international industrial transfer continued to deepen. The construction of 3G and 4G networks in China's communications field, triple play, Internet of Things, and streaming The construction of the media and fiber-optic broadband network continues to deepen, China's national defense science and technology industry maintains more than 15% growth, the implementation of major projects such as scientific research and construction of weapons and equipment, and the development of high-speed railways and strategic emerging industries in China. It is expected that the Chinese module power supply market will continue to maintain an average speed of more than 18%.
