Ljusev, Petar Andersen, Michael Andreas E. Keywords: Flyback Converter, Full-bridge DC-DC Converter, Power Factor Correction.įour-quadrant flyback converter for direct audio power amplification Both simulation and experiment results show that the power factor of this converter achieves up to 0.99 and meets harmonic standard of IEC6. This converter system is designed to produce a 86 Volt of output voltage and 2 A of output current. Flyback converter is operated in discontinuous conduction mode so that it can serve as a power factor correction converter and meanwhile Full-bridge dc-dc converter is used for dc regulator. A flyback converter in resonant mode that features low switching losses, less transformer losses, and low switching noise at high switching frequency is investigated in thisĪC-DC PFC Converter Using Combination of Flyback Converter and Full-bridge DC-DC Converterĭirectory of Open Access Journals (Sweden)įull Text Available This paper presents a combination of power factor correction converter using Flyback converter and Full-bridge dc-dc converter in series connection. The demand of miniaturization of power systems has accelerated the research on high-switching-frequency power converters. In case of prototype 95W converter, the volta.Ī high-switching-frequency flyback converter in resonant mode To suppress such surge voltage, resonant capacitor is divided on primary side and secondary side in the proposed converter. However, relatively large surge voltage is generated in the switching device. A conventional quasi-resonant converter using flyback topology can realize soft switching with simple circuit. This paper presents a quasi-resonant converter with divided resonant capacitor on primary and secondary side of the isolation transformer.
