Abstract

Photovoltaic inverters are the major functional units of the photovoltaic systems. Therefore, efficiency and cost are vitally important in the design, and operation of the PV system. Magnetic components are the bulkiest component and highly affect the efficiency of the galvanically isolated PV inverter and design of such component generally involves a compromise between the reduction of core loss at the expense of increased winding loss or vice versa. The loss characteristics of the magnetic material itself present a fundamental limitation on core loss reduction, implying that the intrinsic reduction of core loss density depends on magnetic material improvements. Hence, the essential tradeoff between cost, performance and physical size must be done by designers to make the most optimal inductor for their design. A high frequency magnetic powder core inductor used in galvanically isolated PV inverter is analyzed with commercially available finite element analysis software, Maxwell - Ansoft. Results obtained from simulation studies are compared with built prototype show good agreement.

分析,设计和评估高频电感,以降低制造成本,提高光伏逆变器的效率
光伏逆变器是光伏发电系统的主要功能部件。因此,在光伏发电系统的设计和运行中,效率和成本是至关重要的。磁性元件是体积最大的元件,对电隔离式PV逆变器的效率影响很大,此类元件的设计通常涉及以增加绕组损耗为代价降低铁芯损耗或反之亦然之间的折衷。磁性材料本身的损耗特性对磁芯损耗的降低产生了根本性的限制,这意味着磁芯损耗密度的内在降低取决于磁性材料的改进。因此,设计人员必须在成本,性能和物理尺寸之间进行必要的权衡,以使其设计最优的电感。采用Maxwell - Ansoft有限元分析软件,对电隔离式光伏逆变器中高频磁粉铁芯电感进行了分析。仿真研究结果与实际样机进行了比较,结果吻合较好。
