In order to meet the needs of large capacity, long distance power transmission and nationwide power grid interconnection, China is making great efforts to develop UHV transmission project. Switching overvoltage directly influences the construction cost and operation reliability of UHV transmission system, how to reduce the switching overvoltage deeply is one of the key technical problems that need...
In this paper, a cost-effective single-phase bidirectional active-filter-integrated AC/DC converter is proposed. It provides simultaneous functions of power factor correction (PFC), DC voltage regulation and active power decoupling for mitigating the low-frequency DC voltage ripple, without an electrolytic capacitor and extra power switches. Such a converter is readily available from a conventional...
