摘要

An AC/DC converter is disclosed. The proposed AC/DC converter generates an output voltage and includes a current ripple eliminator having an input terminal, an energy storage capacitor and an output terminal, wherein the input terminal has an input voltage, the output terminal generates a pure AC component of a voltage feedback signal based on the output voltage, when the input voltage is larger than a first reference voltage, the energy storage capacitor stores a difference between the input voltage and the first reference voltage as an electric energy, otherwise, the energy storage capacitor releases the electric energy to the input voltage, and an operational amplifier operating the AC component and a second reference voltage to determine when the storage capacitor should store or release the electric energy to minimize a ripple of an output power thereof.
