改进型开关磁阻发电机功率变换器及其数据与电能同步传输策略
An improved switched reluctance generator converter and its signal and power synchronous transmission strategy
摘要
Abstract
Given the problem of large output voltage ripple of switched reluctance generator(SRG)system and the demand for safe and reliable data communication in DC microgrid,an improved power converter and power synchronous transmission strategy suitable for SRG is proposed in this article.By appropriately modulating an introduced additional circuit cascaded to the conventional asymmetric half bridge(AHB)converter,the voltage ripple caused by SRG winding commutation is effectively suppressed.The power switch in the additional circuit is modulated using frequency shift keying to generate voltage ripples on the output voltage bus for carry data.Welch method-based power spectrum is adopted to demodulate the transmitted signals.Experimental results show that by rationally modulating the improved SRG converter,the voltage ripples can be effectively suppressed while achieving synchronous transmission of power and data.The proposed data transmission method can also serve as a backup or emergency communication strategy for SRG systems operated in scenarios that require low data communication rates,such as remote switching,status monitoring,and coordinated control.关键词
