随着节能环保需求的增加以及装备升级改造步伐的加快，近年中国中低压变频器行业呈现稳步增长态势，年均增速在15%以上。2009年受金融危机影响，其市场增速有所放缓，全年市场规模同比增长6.3%，至119亿元，其中低压变频器为103亿元，中压变频器为16亿元。2010年随着中国经济的复苏以及下游整体水平的提升，中低压变频器市场较2009年有了大幅提升，预计增速在16%左右。

　　水清木华研究中心《2010-2011年中国中低压变频器行业分析及趋势预测报告》从产业发展环境入手，从市场供应、市场需求、市场竞争三个层面分析了市场情况，并在此基础上分析了15家重点企业。

　　20多年来，中国中低压变频器市场“群雄并起”，除了安川、富士、三菱、三肯等日系品牌外，德国西门子、瑞士ABB、美国爱默生、罗克韦尔等欧美品牌，台达、LG等台韩品牌也纷纷进入，如今国际中低压变频器品牌几乎都已进驻中国，占据国内市场75%的份额。

　　在外资品牌一统天下的局面下，内资品牌不断突围，近年出现了英威腾、汇川技术、欧瑞传动、希望森兰等一批具有竞争优势的企业，内资品牌效应的不断扩大促使其市场份额从2005年的15%提升至2010年的25%。


　　但与外资品牌相比，中国中低压变频器市场集中度还很低，按销售额计算，2009年中国前4家内资企业只占到国内市场6.2%的份额。此外，中国龙头企业的优势领域相对分散，其中，英威腾集中在起重、拉丝和煤炭领域，汇川技术则集中在电梯和注塑机领域。

　　在市场应用方面，中低压变频器几乎涉及国民经济的各个领域，其中起重机械、纺织化纤、油气钻采三大行业的应用最多，占到30%多的份额。随着变频器从“调速”向“节能”的转变，中低压变频器已经拓展到电梯、机床、轨道交通、家电、能源等多个新兴领域。“十二五”期间，中国将继续走“调速节能并举”的路径，这将进一步推动中低压变频器在新兴市场的应用，预计2011年中国电梯用变频器市场规模在11.3亿元，机床用变频器在11亿元、轨道交通用变频器在4000台左右。

Fueled by the increasing requirements of energy saving and environmental protection as well as the accelerated upgrading and alteration of equipment, China’s low & medium-voltage inverter industry has progressed steadily in recent years at an annual average growth rate over 15%. Nevertheless, subject to the financial crisis, it geared down in 2009 and the market size throughout the year rose by 6.3% year on year to RMB11.9 billion, with RMB10.3 billion and RMB1.6 billion attributable to low-voltage inverter and medium-voltage inverter respectively. With the recovery of the Chinese economy and the advancement of downstream industries, the low & medium-voltage inverter market was estimated to grow by 16% in 2010, a substantial increase over 2009.

Starting with the industrial development environment, this report analyzes not only the market supply, demand and competition but 15 key enterprises as well.

Over the past two decades, enterprises at home and abroad have swarmed into the Chinese low & medium-voltage inverter market. Among them, there are Japanese brands like YASKAWA, Fuji Electric, Mitsubishi, and Sanken Electric, European & American brands including Siemens, ABB, Emerson, and Rockwell Automation, as well as Taiwanese and South Korean brands like Delta Electronics, Inc. and LG. Nowadays, almost all the international low & medium-voltage inverter brands have tapped into the Chinese market and occupied 75% market shares.

Domestic brands have been fighting for a place in the market dominated by foreign brands, and a number of competitive enterprises have made their debut in recent years, including Shenzhen INVT Electric Co., Ltd. (INVT), Shenzhen Inovance Technology Co., Ltd. (Inovance), Eura Drives Electric Co., Ltd. (Eura Drives), and Hope Senlan Science & Technology Corp., Ltd. (SLANVERT). The expanding brand effect has promoted the market share of domestic brands to 25% in 2010 from 15% in 2005.


In contrast to foreign brands, domestic low & medium-voltage inverter brands are characterized by an extremely low market concentration ratio, and the top four domestic enterprises accounted for merely 6.2% of the domestic market sales in 2009. Furthermore, leading Chinese enterprises feature relatively scattered superior fields; for instance, INVT highlights hoisting, wire drawing and coal fields, while Inovance gives priority to elevator and injection molding machine fields.  

As for market application, low & medium-voltage inverters nearly involve all the fields of national economy, especially the hoisting machinery, textile & chemical fiber, and oil & gas drilling and exploitation industries which account for more than 30% market shares. Along with the transformation of inverters from “speed control” to “energy saving”, low & medium-voltage inverters have already extended to such emerging fields as elevator, machine tool, rail transit, home appliance, and energy. During the 12th Five-Year Plan period, China will continue to attach equal importance to speed control and energy saving, which will further promote the application of low & medium-voltage inverters in emerging markets. Promisingly, the market sizes of inverters for elevator, machine tool and rail transit will achieve RMB1.13 billion, RMB1.1 billion and 4,000 units respectively in 2011.
