Abstract |
In this paper, the Interleaved AC/DC boost converter using two inductor with voltage-doubler characteristic when it operates with a duty cycle greater than 0.5 is proposed. Generally, the low-line(Input AC 110[V]) operation of the AC/DC boost converter is much less efficient than high-line (Input AC 220[V]) operation. The proposed Interleaved AC/DC boost converter operates as a voltage doubler at low-line. Its low-line range have higher power factor and improved efficiency compared with that of conventional converter. This research proposed the Interleaved AC/DC boost converter for voltage-doubler characteristic. The principle of operation, feature and design considerations is illustrated and the validity of verified through the experiment with a 300[W] based experimental circuit. |
