Frequency communication technology should be Motor The birth of the needs of stepless speed regulation. 50 late 20th century, the U.S. General Electric Company introduced the thyristor power semiconductor components ( SCR SCR), a variable frequency technology provides hardware based on epoch-making significance. Into the 70's, due to limitations of DC motor speed control, AC motor more and more people of all ages. As the market demand, technology is growing and improving. In 1971, the United States, Germany proposed vector control technology, making Inverter AC and DC speed control speed performance can be comparable. In 1973, the United States a power electronics technology in this new discipline, which is the maximum speed driven applications. In 1979, Japan used vector control variable speed system start practical, technology has reached a new level. 80 to the 20th century, thanks to the power semiconductor switching devices and microelectronics technology, inverter performance and reliability increase, decrease production costs, its use began to spread.
Few decades, the power electronic devices from the first SCR (SCR), GTO (gate turn off thyristor), after a BJT (bipolar power transistor), MOSFET (metal oxide field effect tube), SIT (static induction transistor), SITH (SITH), MGT (MOS control transistor), MCT (MOS controlled thyristor), developed to the IGBT (insulated gate bipolar transistor), HVIGBT (resistance High pressure Insulated gate bipolar thyristor), the device's update frequency converter applications prompted broader market followed rapidly.
Into the 80s of the 20th century, the global converter rapid technological change, conversion into mature products are widely used in various industries in the national economy. With China becoming a world factory, manufacturing the rapid development of products for the inverter provides a growing market space, but now, Domestic Converters Market can also be said to be dominated by foreigners, Japanese and Europe and the United States divided up the 80% market share in recent years Taiwan has a number of strong brand frequency performance of the overall domestic brands is still weak.
Frequency was behind the foreign-made "10_15 years" to catch up in recent years, not only has great technical breakthroughs, the development of a number of domestic frequency with international standards, with a considerable competitive edge of enterprises . British Witten, easy energy, Ambition, Zhiguang frequency electric and other domestic manufacturers, with the price advantage, began to occupy more and more market share, but denied the decision made real frequency is a core element of competitive or technical level.
Select the evaluation of domestic (including Taiwan) representative of the frequency brand products and foreign products, the reliability (stability), precision, speed, and parameters for comparison.
Varieties and specifications Varieties and specifications often reflects an enterprise has the technical strength of the high and low. Looking at the mainstream market in the conversion, Europe and the United States brand through modular design, can be very wide power segment. And converter supporting our industry is relatively weak, and domestic brands in terms of technology, manufacturing, industrial design etc. or in the financial strength of all there is a certain gap with foreign brands. Currently, foreign brand market share in the domestic inverter is about 80%. Local inverter company mainly produces V / F control products. For superior performance, high-tech products such as vector inverter, domestic enterprises have not yet developed the most mature product. While the outstanding performance of individual domestic brands such as British Witten, Shenzhen, Chengdu hope Suniland so, have similar high grade inverter products come out, but international giants compared to the range of products, specifications are to be further strengthened and enriched.
Foreign brands and local brands Attractiveness of the Chinese market has also led to Taiwanese capital, foreign intervention, such as Siemens, Mitsubishi, ABB, Taiwan and other general transfer. So far, active in the Chinese market is about more than 40 foreign brands. Emerged nearly simultaneously within the home owned brand, these inverter manufacturers concentrated in coastal provinces such as Guangdong, Shandong, and Jiangsu. Current market share of domestic brands such as Shenzhen, the largest British Witten, Chengdu hope Suniland, Yantai Huifeng and other enterprises in 2006 are breaking 100 million yuan in sales. Shenzhen Ying Wei Tang, Chengdu hope Suniland vector products are launched, including Shenzhen, not only the British Witten Low Vector product of the power specifications have been rich, but also has a mature medium voltage vector product, the extent of its comprehensive product line and complete step by step closer to international top brands, to meet future development needs in all areas.
