Abstract

This paper introduces an improved type of the hybrid-parallel power-factor-correction (HP-PFC) converter proposed before. The performances of the efficiency and the input current waveform have been greatly improved by changing a charging path for the bulk capacitor and balancing the power flow through two transformers to the output. The two transformers supply to the output power is approximated. From the experiment as result, it is confirmed that this improved HP-PFC converter complies with the severer regulation of IEC61000-3-2 Class D. Then, a high efficiency of 90% is achieved for output power of 15 V/6 A under the worldwide line voltage conditions.
