在大规模的分布式可再生能源发电中,变频器在电力电子技术与信息通讯技术双方面都扮演着重要的角色。据发布的数据显示,全球再生能源用变频器市场在2011年为72亿美元的规模。预测今后5年该规模将会倍增,到2017年将超越190亿美元。变频器可使电机系统节电率达30%左右,甚至40%~60%。未来几年中低压变频器需求将保持20%以上的增速,高压变频器行业保持40%以上的增速。绝缘栅双极晶体管(IGBT)是变频器的核心部件,目前国
In large-scale distributed renewable energy power generation, frequency converters play an important role in both power electronics and information communication technologies. According to released data show that the global inverter market with renewable energy in 2011 was 7.2 billion US dollars in size. The scale is expected to double in the next five years, surpassing 19 billion U.S. dollars by 2017. Inverter can save up to 30% of the motor system, or even 40% to 60%. In the next few years, the demand for low-voltage inverter will maintain a growth rate of over 20%, and the high-voltage inverter industry will maintain a growth rate of over 40%. Insulated gate bipolar transistor (IGBT) is the core components of the inverter, the current country
