| Outline of Final Research Achievements |
This project proposes a soft-switching interleaved AC/DC converter with lossless snubber. Recently, AC/DC converters are required unity input power factor characteristic with high efficient operation to prevent the inflow of the harmonic current to the power source. The proposed AC/DC converter improves input current ripple with interleave control. The converter realizes high efficiency by soft-switching operation of all switching devices without large auxiliary resonant circuit.
