高层对话风电或太阳能逆变器市场开发风险和前景 » 上接39页能逆变器在中国的应用，这有市场和政策的因素，中国目前主要发展的是中大功率太阳能发电系统，金太阳示范工程财政补助资金管理暂行办法规定，单个项目装机容量不低于 300kWp。问：开发逆变器需哪些关键元器件？答：逆变器中根据不同功率会采用 IGBT、IGBT模块、MOSFET和高速二极管作为功率变换的主要器件，它们实现高效率大功率变换的核心。在风电变流器中会采用各种解决方案，如大电流模块IHM，其最大电流可达3600A 1700V；在 EconoPack+和EconoDUAL3封装中有450A 1700V不同电路结构的模块，在这些封装中都有适用于风电的第四代IGBT4的产品。新的模块封装形式如PrimePack也成了风电变流器市场的新宠，这些新技术的应用会使得风电变流器的可靠性和寿命会提高，成本也会降低。提高中大功率太阳能发电系统能源效率，逆变器是一个重要环节，它是保证太阳能转换效率和投资回报的关键因素。国内外已有不少太阳能逆变器生产厂商，产品也日趋成熟，高能效的功率变换技术不断引入，新一代的 IGBT、IGBT模块、MOSFET和碳化硅二极管的使用，使得效率的标杆不断被刷新。请关注：太阳能发电市场机遇我也要点评相关阅读 • 英飞凌推出全球最小的3G智能手机HSPA+解决方案 • 飞思卡尔与英飞凌同台演讲：汽车电子发展的四大趋势 • 英飞凌推出全球最小低功耗全集成GPS接收前端模块 HALF PAGE AD (horizontal) 215mm x 139mm 42 国际电子商情 | 2010年4月 | www.esmchina.com http://www.esmchina.com/STATIC/SITE/DigitalEdition_201004.HTM#tj http://www.esmchina.com/ART_8800105493_1400_2405_0_0_0730000c.HTM http://www.esmchina.com/ART_8800106005_1100_2607_0_4200_d37b9199.HTM http://www.esmchina.com/ART_8800105936_1500_2201_3902_0_3df07bb8.HTM http://www.hi-hone.com http://www.hi-hone.com http://www.hi-hone.com http://www.hi-hone.com http://www.esmchina.com
