[1]新能源大功率高压直流并网变换器

Publisher:科学出版社

Description of Publication:本书重点阐述了非隔离型与隔离型大功率高压直流变换器的电路拓扑与相应的控制技术。首先,针对非隔离型方案,提出谐振开关电容升压和LC并联谐振升压两种结构,分别实现开关管的零电流开关(ZCS)和零电压开关(ZVS)。其次,针对隔离型方案,提出一种支干分流思想,实现主开关管的ZCS,显著降低了变换器的开关损耗。基于支干分流思想,提出一系列ZCS直流升压变换器。再次,针对定脉宽变频调制LC串联谐振变换器,分析其高频变压器磁芯磁密变化情况,并提出一种非对称定脉宽变频调制策略,彻底消除了高磁密工作模式,避免了变压器饱和问题。最后,研制了模块化IPOS型、高频谐振型和中频型三套±35kV/500kW光伏直流并网变换器,并在中国电力科学研究院有限公司张北新能源基地成功示范应用。
