| Summary: | 碩士 === 國立臺灣科技大學 === 電子工程系 === 99 === The main purpose of this thesis is to study and implement a 300 W continuous current conduction mode (CCM) power factor corrector (PFC) with an external sample and hold (S/H) circuit design. A zero crossing detection (ZCD) circuit is designed to avoid wrong sampling due to electromagnetic interference (EMI) issue. The proposed PFC converter has the advantages of low input current total harmonic distortion (THD) and superior dynamic response features.
Operation principles and design considerations of the proposed PFC converter are analyzed and discussed in details. Experimental results of a laboratory prototype are shown to verify the feasibility of the proposed topology and control schemes. The prototype can substantially satisfy the requirements of the ENERGY STAR computer program.
