摘要

带有高效同步磁阻发电机(SRG)的高效隔离式 DC/DC 转换器是直流微电网系统的最终解决方案。本文对具有同步磁阻发电机性能的隔离式 DC/DC 转换器进行了设计和建模。在发电机侧,无功功率和有功功率被用作脉宽调制(PWM)控制变量。此外,还使用了磁通估计器。三相 PWM 整流器采用空间矢量调制 (SVM),开关频率恒定,用于直接功率控制。此外,论文还对结果进行了实验验证。论文还提出,要实现混合可再生能源系统应用的高性能,需要高效的功率转换器和同步磁阻发电机。

Modeling the System for Hybrid Renewable Energy Using Highly Efficient Converters and Generator
High-efficient isolated DC/DC converters with a high-efficiency synchronous reluctance generator (SRG) are the ultimate solutions in DC microgrid systems. The design and modeling of isolated DC/DC converters with the performance of SRG are carried out. On the generator side, reactive and active powers are used as pulse width modulation (PWM) control variables. Further, the flux estimator is used. Three-phase PWM rectifier is used by applying space vector modulation (SVM) with a constant switching frequency for direct power control. Further, the paper also includes the experimental validation of the results. The paper also proposes that highly efficient power converters and synchronous reluctance generators are required to achieve high performance for hybrid renewable energy systems applications.
