In 2012, the market share of variable frequency household appliances continued to expand, with the production and sales rising rapidly. The frequency of launching new products was noticeably accelerated. The concern of household appliance whole machines to frequency conversion technology was unprecedented. The purchase of inverter controllers and variable frequency components increased significantly. In 2012, the production and sales of inverter controller of Ningbo German Industrial Frequency Conversion Technology Co., Ltd. witnessed a rapid growth of 200%. At present, the growth momentum is still continuing. After the Spring Festival in 2013, German industry's production and sales department immediately restored the busy days of the past. German industry sales person in charge told reporters: "German industry is the development, production and sales of high-tech enterprises, and complete machine business cooperation model is very mature, coupled with technical reserves over the years, has built a heavy volume growth According to reports, in 2012, Germany's production of inverter controller 1.3 million units, 60% of the products supporting air-conditioning production, 15% for the refrigerator, 10% Supporting washing machines, scattered the rest of the products used in mobile air conditioners, dehumidifiers, small appliances and other fields. Wuxi Crystal Technology Co., Ltd. and the earliest mainly for the refrigerator market demand for the development of inverter controller, in recent years the scope of business has been extended to the drum washing machines, heating appliances and small appliances areas. In 2012, the crystal frequency conversion control business progressed smoothly and achieved steady growth. "The true realization of leapfrog inverter household appliances should be in 2013." and Crystal Technology Director Xu Gongyun said that "in 2012 the complete appliance business to complete the concept of frequency conversion market, put the right amount of inverter test market reaction, The contrarian growth of inverter household appliances will surely attract more machine manufacturers to increase their investment.This trend is especially evident when the whole machine manufacturers make annual production and sales plans by the end of 2012 and early 2013. Many complete machine companies have come to negotiate Cooperation projects, and crystal orders increased significantly. " "There is absolutely no need to worry about the prospect of inverter controller in the field of home appliances, and Shin-Yuan has been engaged in the production of inverter controller for many years and the sales volume has been steadily increasing. In the first two months of 2013, we have seen a significant increase in the procurement of complete machine companies . "Shanghai Xinyuan Electric Co., Ltd. Wang Xiujuan said that the current annual supply of new source frequency controller 200,000 units, divided by application areas, air-conditioning accounted for 60%, washing machines accounted for 20%, other household appliances accounted for The ratio is 20%. " According to Li Ming, director of Xi'an Application Center of International Rectifier (hereinafter referred to as IR), in 2012, the production business of IR frequency conversion control devices achieved an average increase of 30% over previous years. "In 2012, the inverter business of household appliances in semiconductor companies basically saw a growth of 10% ~ 30%." The inverter products used in the field of home appliances mainly include power devices such as control, driving and reverse power, as well as intelligent power modules and IGBTs Insulated Gate Bipolar Transistors) and the like. At the same time, IR can provide complete set of inverter control scheme for the whole machine company. At present, IR's inverter control products have been widely used in air conditioner, refrigerator, washing machine, dishwasher and electric fan. Among them, the highest proportion of products supporting air-conditioning production, accounting for almost IR electrical control 90% of inverter business. "In addition to the continued rapid growth of applications in air conditioners, Fujitsu Semiconductor introduced its main controller MCUs for use in washing machines and refrigerators in 2012." Fujitsu Semiconductor (Shanghai) Co., Ltd. product marketing manager Peng Tao told reporters: Fujitsu Semiconductor MCU R & D manufacturers, the main controller MCU is the company supporting the main production of household appliances, but also the core of the inverter control unit.Fujitsu semiconductor to broaden the field of product applications earlier, has accumulated rich experience in the design and production, This laid the foundation for our products to gain more market share in various home appliance applications. "According to reports, Fujitsu semiconductor main controller MCU applications in the Chinese market is divided into three major parts of home appliances, consumer electronics and industrial. Among them, the main controller supporting household appliances MCU about 1/3. In the field of home appliances, Fujitsu Semiconductor main controller MCU about 60% air conditioning, 30% matching washing machines, 10% matching refrigerator. Play expertise, select the right entry point Reporters found during the interview, currently concerned about the production of household appliances inverter controller can be divided into three camps - semiconductor manufacturers, inverter controllers and 整机 companies focus on frequency conversion technology development subsidiaries. In fact, in the initial cooperation mode, these three forces respectively control the three major production links of the frequency conversion household appliances - the semiconductor manufacturers provide the variable frequency components and the frequency conversion controller enterprises complete the design of the frequency conversion scheme and the assembly and production of the frequency conversion control board Machine companies are responsible for matching development of home appliances. In 2012, these three forces are desperately increasing their control over the field of household appliances' inverter control. Each has its own place in the industrial chain.
