Domestic high-lift converter market has long been the foreign Brand Monopoly Expected to break the ice, Beijing, Industrial Control Lanhai innovative and Tsinghua limited liability company power electronics and Motor Control key state Laboratory Developed in cooperation with independent Intellectual property rights Frequency of elevator control system has been implemented on an experimental prototype running smoothly. The results show that the performance of its technology meets or exceeds internationally renowned brands.
Inverter is a key component of the modern elevator control, elevator technology is the highest content of the highest value-added components. China is the world's largest producer of the first elevator, but the lift transducer has been imported. Even foreign joint ventures or wholly-owned elevator company, the use of inverter are directly purchasing foreign products. Although domestic companies have launched many low-end General Inverter, but the lack of core inverter control software technology, development of high-end special frequency converter has been little progress, which makes it difficult to lift the domestic elevator companies for in-depth product development, only a limited market for profit. At present, the elevator special inverter 90? Of the domestic market share to foreign enterprises and domestic joint ventures, product monopoly, which, as the elevator inverter "head" is also the most profitable parts of the elevator control system frequency, almost all foreign products the world.
On the domestic market demand by now lift 100 000, 1 Taipower Ladder Converter 10,000 yuan terms, lift inverter of at least 1 billion yuan annual demand.
Lanhai companies rely on power electronics and motor control of Tsinghua University State Key Laboratory of long-term technology accumulation and the introduction of foreign Talent Unique technology, one stroke frequency control algorithm in high-end software technologies to achieve a critical breakthrough and successfully used this software dedicated frequency lift control system, and achieved initial results. Once the technology and industrialization, will lift from the monopoly of foreign high-end frequency converter in the field squeeze the Chinese people their own space.

Lift converter is not only a great market space, there is a significant Energy Effect. The inverter is used in the elevator more than 40% energy saving can be realized. At present, China uses the elevator, only 1.92% of the lift using variable frequency control of energy-efficient elevator host, and use the lift more than 10 years and both are serious power type. Elevators in China in 2004, about 55 million, the annual consumption of about 30 billion kwh. If 10 million to replace the lift into energy-saving variable frequency control host, according to Saving 40% of the conservative calculation, the annual electricity savings will reach 240 million kwh; if all elevators used in all energy-saving variable frequency control console, saving 600 million a year at least -8 billion kilowatt hours.
