Abstract

In this paper, the 2MW PMSG-based wind conversion system with bidirectional full scale frequency converter comprised of two back-to-back inverters is considered. The efficiency and total volume comparison have been conducted for Si-and SiC-based converters. The comparison presented is a fair comparison, meaning that the converters are designed with modules of the same power ratings. Wind energy systems are compared both for the same switching frequency (low switching frequency suitable for IGBT modules), but are considering also SiC-MOSFET based converter working at high switching frequencies. The comparison is done in PLECS simulation tool, using the PLECS libraries for different modules obtained from the manufacturers’ experimental data. The results show the benefits of using the SiC-based converter. In fact, when compared to the Si-based converter the efficiency is practically the same, while there is the reduction of 2.85 times in the total volume necessary for the passive components.

风电全量程变频器中的大功率SiC模块:与基于igbt的变频器效率比较

本文考虑了由两台背靠背逆变器组成的双向满量程变频器的2MW pmsg型风力发电系统。对硅基和硅基变换器的效率和总体积进行了比较。所提供的比较是一个公平的比较，这意味着转换器是用相同额定功率的模块设计的。风能系统在相同的开关频率下进行了比较(低开关频率适用于IGBT模块)，但也考虑了在高开关频率下工作的基于SiC-MOSFET的转换器。在PLECS仿真工具中进行比较，利用PLECS库对不同模块从厂商实验数据中获得的数据进行比较。结果表明了采用基于sic的变换器的优点。事实上，与硅基变换器相比，效率几乎相同，而无源元件所需的总体积减少了2.85倍。
