2014年对于电力电子行业来说,整体业绩喜忧参半。一方面,下游行业设备投资意愿不强,订单增速放缓,导致变频器市场出货量下滑。国内变频器企业急需缩小技术差距,加强质量控制,攻占高端市场。另一方面,IGBT国产化曙光再现,南车株洲所8英寸IGBT芯片正式下线,即将批量化生产,IGBT中国芯正在逐步得到解决。本土变频器高端市场占有率仍存在差距近年来,本土变频器品牌经过多年蓄力,逐步扩大市场占有率,进口产品的市场份额已经被国内变频器企业超 2014 for the power electronics industry, the overall performance is mixed. On the one hand, the downstream industry investment in equipment is not strong, orders slowed down, leading to the inverter market shipments decline. Domestic inverter companies need to narrow the technological gap, to strengthen quality control, capture the high-end market. On the other hand, the dawn of IGBT localization made its appearance. The 8-inch IGBT chip of Zhuzhou Zhuzhou CSR Co., Ltd. was formally put into mass production. The IGBT China core is being gradually solved. In recent years, local inverter brand after years of empowerment, and gradually expand market share, the market share of imported products has been the domestic inverter business super
