Switching power supply is a kind of power supply which uses modern technology to control the time ratio of switching on off, maintain stable output voltage. Switching power supply is generally composed of pulse width modulation control IC MOSFET. With the development innovation of power electronic technology, the technology of switching power supply is constantly innovating. At present, switching power supply is widely used in almost all electronic equipment with the acteristics of small size, light weight high efficiency. It is an indispensable power supply mode for the rapid development of electronic information industry.

According to the data collected sorted out by China Power Supply Association, the output value of switching power supply (mainly including consumer switching power supply, industrial switching power supply, communication power supply PC power supply, the same below) in 2008 reached 85.5 billion yuan, in 2009 reached 93.1 billion yuan, an increase of 8.8%; In 2010, it reached 102.7 billion yuan, an increase of 10.3. Even under the impact of the global financial crisis in 2009, the output value of the whole industry still reached 106.1 billion yuan, maintaining a growth rate of more than 5. In 2010, with the implementation of a series of national macroeconomic stimulus policies the stabilization of the global economy, Chinas electronic information industry quickly recovered its momentum of development, Chinas power industry took advantage of the trend, with the output value reaching 117.2 billion yuan the growth rate exceeding 10

This kind of modular power supply has many advantages, such as miniaturization, light weight, high power density / conversion efficiency, wide range of input voltage, less heat consumption so on. It develops rapidly in recent years in the electronic industry. Switching power supply products are divided into stardized products non stardized products. Generally speaking, stardized products have large order quantity, low gross profit fierce competition, while non stardized products have small order quantity, but high gross profit small competition. Stardized products are mainly used in consumer electronic products, PC power supply other fields, rather than stard customized product applications communication power supply, new energy industrial power supply other fields.

Stardized switching power supply enterprises generally organize production according to the orders of customers, enterprises generally do not have inventory. Manufacturing according to order refers to the production mode of modifying design, manufacturing assembly, or re developing design based on the existing product scheme after receiving the customers order, finally providing the customer with customized products. After receiving the customers order, according to the specific requirements of the order, the enterprise designs customized products that can meet the customers special requirements. The ion of suppliers, the requirements of raw materials, the design process, the manufacturing process the delivery of finished products are all determined by the customers order. There are many types of switching power supply products, general enterprises can not gain advantages in each market segment. In addition to the fierce competition of power adapter mobile phone ger, the gross profit of these stardized products is relatively low, all enterprises have their main market segments, actively explore new areas, can achieve good profit margin.

Different from mass customization, customized switching power supply is more of small batch customization. In order to better control the cost quickly provide customers with low-cost high-quality customized products, it puts forward higher requirements for the enterprises R & D, production management purchasing ability. Therefore, the enterprise must have agile product development design ability raw material purchasing ability, which is specially for a kind of production The traditional rigid production line of product design will also be replaced by the flexible production line which can meet the diversified personalized manufacturing requirements.

Because the switching power industry is mainly customized, the sales orders of enterprises are closely combined, so the sales behavior mostly occurs before the product manufacturing. At the same time, R & D stard products to the market customers, actively exp the electronic industry customers, show the companys R & D design capabilities, production scale quality management capabilities become an important means of enterprise sales. At present, the ways to exp sales channels in switching power supply industry mainly include participating in industry exhibitions, promoting in professional print media industry websites, recommending customers to each other, while obtaining high-quality customer resources is the most direct embodiment of enterprise strength.
