摘要: 本論文使用全橋式電路做為雙向功率潮流轉換器,實現於並聯操作中,運用下降控制法,作為各轉換器間平均分配電流的控制方法,在無須改變原有的單模組控制架構下,且各控制器之間不互相連接,各轉換器為獨立運作的情況下,可以輕易的達到良好的電流追隨及電壓調節,並在此架構下,討論三種切換策略,分別為雙極切換策略單極切換策略以及相位導向切換策略,對於並聯操作中所產生的環流問題,以及影響的各種可能因素進行討論分析。最後,為了進一步了解實際的可行性,建立了一個以雙並聯轉換器電路為基礎,驗證所得的結果。
In this study, the droop method is used to share the current for parallel bidirectional full-bridge converters. Each converter is operating independently without connections between modules and without modification of the control structure. In the parallel converters, the effect of switching strategy on the reduction of circulating current is studied. The simulation and experimental waveforms are also provided to demonstrate the results.
