Switching power supply technology has a wide range of applications

With the rapid development of power electronics technology, the relationship between power electronics equipment and people's work and life has become increasingly close, and electronic equipment is inseparable from reliable power supply. Into the 80s, computer power supply fully realized the switching power supply, the first to complete the computer's After the power generation, the switching power supplies of the 1990s entered various electronic and electrical equipment fields one after another. Program-controlled switches, communications, power supplies for electronic testing equipment, and power supplies for control equipment have all been widely used as switching power supplies, and have facilitated the rapid development of switching power supply technologies. .

Switching power supply is a type of power supply that uses modern power electronics to control the turn-on and turn-off time of the switch and maintain a stable output voltage. The switching power supply is generally composed of a pulse width modulation control IC and a MOSFET. With the development and innovation of power electronics technology, switching power supply technology is also constantly innovating. At present, the switching power supply manufactured by Nanjing Pengtu Power Supply Company is widely used in almost all electronic devices due to its small size, light weight, and high efficiency. It is an indispensable power supply mode for the rapid development of the electronic information industry today.

According to the data collected by the China Institute of Power Sources, the national switching power supply (mainly including consumer switching power supplies, industrial switching power supplies, communication power supplies, and PC power supplies, the same below) reached an output value of 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 in 2009 under the impact of the global financial crisis, the industry's output value still reached 106.1 billion yuan, maintaining a growth rate of more than 5. In 2010, following the implementation of a series of macro-stimulus policies of the country and the stabilization of the global economy, the electronic information industry in China soon resumed its momentum of development. The Chinese power industry has taken advantage of this trend, and the output value reached 117.2 billion yuan. More than 10.

Nanjing Pengtu, a module power supply with 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 has developed rapidly in the electronics industry. Switching power supply products are divided into standardized products and non-standardized products. In general, standardized product orders have large volume, low gross profit, and fierce competition, while non-standardized product orders have smaller volume, but have higher gross profit and less competition. Standardization products are mainly used in consumer electronic products, PC power supplies and other fields, rather than standard custom product applications and communications power supplies, new energy sources, and industrial power supplies.

Standardized switching power companies generally organize production according to customer orders, and companies generally do not have inventory. Make-to-order refers to the modification of design, manufacturing and assembly on the basis of an existing product plan after receiving a customer order, or re-development of the design, and ultimately provides the customer with a customized product production method. After receiving orders from customers, the company designs customized products that meet the specific requirements of customers according to the specific requirements of the orders. The selection from suppliers, raw material requirements, design process, manufacturing process, and delivery of finished products are all determined by customer orders. . There are many types of switching power supply products, and the average enterprise cannot gain an advantage in every market segment. Apart from the intense competition in standardized products such as power adapters and mobile phone chargers, each company has its main attack market segment and is active. Open up new areas and get better profit margins.

Different from mass customization, customized switching power supplies are more customized in small batches. In order to better control costs, customers are provided with low-cost, high-quality customized products quickly, and their R&D, production management, and procurement capabilities are presented. With higher requirements, companies must have agile product development and design capabilities and raw material procurement capabilities. The traditional rigid production line designed specifically for a product will also be replaced by a flexible production line that can meet diverse and individualized manufacturing requirements.

Since the switching power supply industry focuses on customization, sales and orders are closely integrated with the company, so sales behavior occurs before the product is manufactured. At the same time, R&D standard products are being promoted to the market and customers, and actively expanding customers in the electronics industry, showing that R&D and design capabilities, production scale, and quality management capabilities of the company have become an important means for corporate sales. At present, the switching power supply industry's ways to expand sales channels include participation in industry exhibitions, promotion in professional print media and industry websites, and mutual customer referrals, and obtaining quality customer resources is the most direct embodiment of corporate strength.
