Three‐Way Equal Filtering Power Divider for Modern Communication Systems

Engineering Reports
This article proposes a three‐way (3‐way) equal filtering power divider (FPD) employing the microstrip compact folded‐arms square open‐loop resonator (FASOLR). The proposed FPD evenly distributes an input signal into three equal output signals.

Open-loop mode resonance risk determination based on measurement model

电力工程技术
The open-loop mode resonance theory is an important theoretical achievement to explain the mechanism of system instability caused by the grid connection of permanent magnet synchronous generator (PMSG), but the determination of the resonance risk of open-loop mode based on the black box measurement model is rarely introduced in its theoretical research.
