本文研製一部具有功因校正的單相SEPIC交流/交流轉換器,硬體電路主要以雙向開關切換達成交流/交流轉換,並使用數位訊號處理器TMS320F2808為核心,藉由電壓及電流的迴授達成前饋與閉迴路控制,以提供穩定的輸出電壓及提高輸入側的功因。本文針對相關原理及設計方法進行探討,完成一部輸出交流110伏特,最大功率150瓦,功率因數0.98以上的單相交流/交流功因校正電路。實測結果與理論分析相當接近,說明本文所提方法的可行性及正確性。
The thesis studies a single-phase, SEPIC based, ac/ac power factor corrector. The hardware is implemented by using bi-directional semiconductor switches to achieve ac/ac conversion. In addition, a digital signal processor, TMS320F2808, is used as a control center. By using the voltage and current feedback and the feed-forward control method, a fixed output ac voltage with high input power factor can be obtained. The basic principle and design method are discussed. A single-phase ac/ac power factor corrector circuit with 110V, 150W, 0.98 power factor has been implemented. Experimental results can validate the theoretical analysis to show the feasibility and correctness of the proposed methods.
