摘要: This paper presents an analog implementation of a fast controller for unity-power-factor (UPF) AC/DC converter. Unlike low bandwidth controllers associated with many state-of-the-art UPF converters this can exercise control action at rate comparable to the switching frequency rather than line frequency. In order accomplish while maintaining unity power factor, employs ripple-feedback cancellation scheme. addition responding faster disturbances, facilitates replacement bulky bus capacitors smaller, less expensive alternatives. >
