On November 16th, Yang Baolin, the director of the LED Special Committee of Zhongshan Chamber of Commerce of Zhongshan City, accompanied by Yang Baolin, General Manager of Shenzhen Feijieshi Technology Co., Ltd., accompanied by Lu Peng, General Manager of Marketing and Sales Center of Wuxi Huarun Huajing Microelectronics Co., Ltd., Power Semiconductor R&D Center General Manager Wang Ronghua, project director Wan Hui and other 7 people visited the Executive Committee of the LED Special Committee: Zhongshan Tobo Photo, November 16th, Zhongshan City, Hunan Chamber of Commerce LED Special Committee, Shenzhen Feijieshi Technology Yang Baolin, general manager of the company, accompanied by Lu Peng, general manager of Wuxi Huarun Huajing Microelectronics Co., Ltd. market and sales center, Wang Ronghua, general manager of Power Semiconductor R&D Center, and Wan Hui, project director, visited the executive committee of LED special committee. : Zhongshan Tobo Lighting Appliance Co., Ltd., executive president and general manager of the company Long Kaixiang warmly received everyone, and reached a strategic cooperation around the price increase of raw materials and the newly developed MOSFET materials of China Resources. â–²Long Kaixiang (fourth from right), executive director of LED Professional Committee of Hunan Chamber of Commerce in Zhongshan, took a group photo with the leader of China Resources Corporation. â–² Chairman of the LED Professional Committee of Zhongshan Chamber of Commerce in Zhongshan City, President Long Kaixiang, introduced the leadership of Tubo Electric to the leaders of China Resources The two major brands of flow source and energy saving and the overall planning of LED drive power, and introduced: With the maturity of LED market and technology, its related technology applications have penetrated into various fields. The driving power source is known as the heart of LED lighting fixtures. The introduction of new technologies, improving efficiency and reducing costs are the main development trends in the future. MOSFETs play a very important role in the promotion and rapid popularization of LED driving power supplies. â–² Yang Baolin, director of the LED Professional Committee of the Hunan Chamber of Commerce in Zhongshan, Yang, learned from the front line: At present, the entire electronics industry is only crazy, no joy. Because, whether it is PCB, packaging companies, or IC or MOSFET, etc., are crazy price increases, price increases, spent in the price increase. Also on this day, on November 11th, the dunning letter and the letter of suspension were also coming, and the electronics industry has reached the most critical moment. The most painful thing is that the supplier tells you that it will go up later. Faced with these problems, China Resources Huajing has given customers the perfect solution. The company has spent more than 20 million to purchase exclusive super-junction MOSFET patents. If customers use China Resources' super-junction MOS, it will be more efficient than the past planar MOSFETs. If you don't raise the price, you can also reduce the cost by 20% for the customer. This series of MOSFETs enables an optimized combination of Multi-EPI and Deep Trench super-junction processes, with better EMI and lightning surge resistance compared to conventional superjunction products, and device merit (Qgd*Rdson) Better than ordinary super junction, it has a great effect on the performance of LED power supply. Mr. Yang said: At present, there are many companies that do super-junction MOSFETs on the market, but they all have the same problems, they can't solve the problem, and they can't pass the safety regulations, and the lightning surges, etc., while China Resources Huajing bought the patents. A self-developed set of super-junction MOSFETs perfectly solves this problem. â–²Lu Peng, General Manager of Marketing and Sales Center of Wuxi Huarun Huajing Microelectronics Co., Ltd. Lu Peng, general manager of Huarun Huajing Sales Center, believes that this MOSFET can be compared with imported products regardless of safety factor and technical parameters, and the price is very grounded. After the Zhongshan LED leading enterprise Tubo Electric tried the super-junction MOSFET, Mr. Long Kaixiang, the general manager of the company, also gave positive evaluation and affirmation to the performance parameters of the product. Long always believes that if China Resources Huajing can solve the problem of EMI and lightning strikes, it is indeed at the leading level in the industry. Later, it will recommend the Huarun Huajing brand to more members of the Hunan Chamber of Commerce. According to Lu Peng, general manager of China Resources Huajing Micro Sales Center, as the highest-end product in MOSFET, super-junction MOSFET products can be applied to high-end switching power supplies in computer servers, communication equipment, flat panel displays, high-power white goods, energy-saving lighting and other fields. It can also be used in AC to DC equipment such as Volkswagen power adapters and chargers. With the global awareness of energy conservation and environmental protection, high-efficiency and energy-saving products have become the mainstream of market development. Accordingly, various types of MOSFET power devices with energy saving effects are increasingly being applied to complete electronic products. In MOSFET power device products, the market demand for high-voltage, high-current super-junction MOSFET devices is the fastest growing, but the current high-voltage, high-current super-junction MOSFET device market is monopolized by a few European and American manufacturers. The most important reason for being monopolized is the lack of such products in China and the lack of high-end talents in this field. Lu Peng said that this also prompted Huajing to speed up the pace of research and development. â–²Wu Ronghua, general manager of Wuxi Huarun Huajing Microelectronics Co., Ltd. Wang Ronghua, general manager of China Resources Micro-R&D, Wang Ronghua introduced: In design, Huajing's new high-voltage super-junction MOSFET products combine two kinds of super-junction technology, with low Miller charge, switch The high speed, safe working area and diode reverse recovery characteristics keep the high voltage resistance of the original high voltage MOSFET products. At the same time, the loss of the new device as a high-speed electronic switch is extremely low, and the energy conversion efficiency exceeds 95%. Has better EMI and lightning surge characteristics. This technology can be seen as a transformation and upgrading of the domestic discrete devices field, which will fill the gap in China's related fields. At present, DELL, Lenovo, etc. have chosen to cooperate with China Resources Huajing. In addition to the safety factor and conversion rate comparable to strong foreign countries such as Europe, America and Japan, we also have the advantage that the price will be 50% lower than the imported similar products. Wang Ronghua said that this makes super-junction MOSFETs widely used in consumer electronics. It is reported that Wuxi Huarun Huajing Microelectronics Co., Ltd. is the national key high-tech enterprise responsible for power semiconductor device business of China Resources Group. It is the vice president unit of China Semiconductor Association's discrete device branch, producing the famous Huajing brand discrete devices. China Resources is a diversified holding company group registered and operated in Hong Kong. Its predecessor was the Union Bank established in Hong Kong in 1938. In 1948, it was renamed as China Resources Corporation. In 1952, the affiliation was changed from the Central Office of the CPC to the Central Trade Department. (now the Ministry of Commerce). In 1983, China Resources (Group) Co., Ltd. was reorganized. In December 1999, it was decoupled from the Ministry of Foreign Trade and Economic Cooperation and listed as a central management. In 2003, it was directly managed by the State-owned Assets Supervision and Administration Commission of the State Council and was listed as a key state-owned enterprise. Correspondent: He Liangzhou
