本文研製一部具功因校正的數位化直流電源供應器,硬體電路主要包括功因校正電路及相移式全橋電路。文中以積體電路UC3854作為功因校正的控制器,並使用數位訊號處理器TMS320LF2407A完成閉迴路控制。本文中針對相關原理及設計方法進行探討。最後完成一部輸出直流48V,輸出功率864W,輸入電源側功率因數0.99,且輸入電流諧波滿足EN-61000-3-2規範的電源供應器。實測的結果與理論分析相當符合,說明本文的可行性及正確性。
The thesis implements a digital DC power supply with power factor correction. The hardware circuit includes a power factor correction circuit and a phase-shift full-bridge circuit. In the thesis, a UC3854 is used to control the power factor of the input source. In addition, a TMS320LF2407A is used to execute the closed loop control algorithms. The detailed principles and design methods are included. Finally, a DC power supply with 48V/864W, 0.99 power factor, satisfactory EN-61000-3-2 Standards is implemented. Experimental results can validate the theoretical analysis to show the feasibility and correctness of the thesis.
