Analysis on the development status of switching power supply technology industry chain

　　According to data collected by the China Power Supply Society, the output value of national switching power supplies (mainly including consumer switching power supplies, industrial switching power supplies, communication power supplies, PC power supplies, the same below) reached 85.5 billion yuan in 2008, and reached 93.1 billion yuan in 2009. 8.8; reached 102.7 billion yuan in 2010, an increase of 10.3. Even under the impact of the global financial crisis in 2009, the industry's output value still reached 106.1 billion yuan, maintaining a growth rate of more than 5. In 2010, with the implementation of a series of national macro-stimulus policies and the stabilization of the global economy, my country's electronic information industry quickly resumed its development momentum. China's power supply industry took advantage of the situation, with an output value of 117.2 billion yuan, a growth rate of More than 10.

　　This kind of modular power supply, which has many advantages such as miniaturization, light weight, high power density/conversion efficiency, wide input voltage range, and low heat consumption, has developed rapidly in recent years and is developing rapidly in the electronics industry. Switching power supply products are divided into standardized products and non-standardized products. Generally speaking, standardized products have larger order quantities, lower gross profits, and fierce competition, while non-standardized products have smaller order quantities, but higher gross profits and less competition. Standardized products are mainly used in consumer electronics, PC power supplies and other fields, while non-standard customized products are used in communication power supplies, new energy and industrial power supplies.

　　Standardized switching power supply companies generally organize production according to customer orders, and companies generally do not keep inventory. Manufacturing to order refers to a production method in which after receiving a customer order, the design, manufacturing and assembly are modified based on the existing product plan, or the design is re-developed, and finally customized products are provided to the customer. After receiving the customer's order, the company will design customized products that can meet the customer's special requirements according to the specific requirements of the order. The selection of suppliers, raw material requirements, design process, manufacturing process, and delivery of finished products are all determined by the customer's order. . There are many models of switching power supply products, and ordinary companies cannot gain advantages in every market segment. Except for standardized products such as power adapters and mobile phone chargers, which are highly competitive and have low gross profits, each company has its main market segments and actively Exploring emerging areas can lead to better profit margins.

　　Different from mass customization, customized switching power supply is more of a small batch customization. In order to better control costs and quickly provide customers with low-cost, high-quality customized products, it puts forward some requirements for the company's R&D, production management and purchasing capabilities. Therefore, enterprises must have agile product development and design capabilities and raw material procurement capabilities. Traditional rigid production lines designed specifically for one product will also be replaced by flexible production lines that can meet diverse and personalized manufacturing requirements.

　　Since the switching power supply industry is mainly customized, the company's sales and orders are closely integrated, so sales actions mostly occur before product manufacturing. At the same time, it has become an important means for corporate sales to develop standard products and promote them to the market and customers, actively expand customers in the electronics industry, and demonstrate the company's R&D and design capabilities, production scale and quality management capabilities. Currently, the main ways for the switching power supply industry to expand sales channels include participating in industry exhibitions, promoting in professional print media and industry websites, and recommending each other to customers. Obtaining high-quality customer resources is the most direct reflection of a company's strength.
