摘 要
高效同步磁阻发电机（SRG）与高效隔离DC/DC转换器相配合是直流微电网系统的最佳解决方案。本文对具有SRG性能的隔离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用作脉宽调制（PWM）控制变量，进一步采用了通量估计器。三相PWM整流器通过应用具有恒定开关频率的空间矢量调制（SVM）用于直接功率控制。此外，本文对所提方法进行实验验证。研究结果表明，混合可再生能源系统的应用，需要高效的功率转换器和同步磁阻发电机来实现高性能。
Abstract
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.
