我国高压变频器的发展现状 

　　目前，我国约有20家左右的高压大功率变频器生产厂家，如利德华福、东方凯奇（现东方日立）、成都佳灵、中山明阳、广州智光、上海科达、山东风光、合康益盛、九洲电气等。 

　　由于美国罗宾康公司没有在中国申请*保护，因此绝大多数厂家都采用他的技术即单元串联多重化结构。深圳市英威腾电气股份有限公司则采用拥有自主知识产权的技术，开发出CHH系列矢量控制的高压变频器，2009年已试生产了40台，2010年已经批量生产了107台。 

　　随着技术研究的进一步深入，在理论上和功能上国产高压变频器已经可以与进口变频器相比肩，但是受工艺技术的限制，与进口产品的差距还比较大，这些状况主要表现在如下几个方面： 

　　（1）国外各大*的产品正加紧占领*，并加快了本地化的步伐。  
（2）具有研发能力和产业化规模的企业逐年增加。  
（3）国产高压变频器的功率也越做越大，目前国内大能做到8000KW。  
（4）国内高压变频器的技术标准还有待规范
