碩士 === 國立臺灣科技大學 === 電機工程系 === 96 === 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.
