A Feedforward Voltage Control Strategy for Reducing the Output Voltage Double-Line- Frequency Ripple in Single-Phase AC–DC Converters

This article proposes a feedforward voltage control strategy (FVCS), aimed to reduce the output voltage double-line-frequency ripple and the output capacitance of the single-phase ac–dc power factor correction (PFC) converters. It is known that a large capacitance is required to reduce the voltage ripple but it results in low power density. With the proposed FVCS achieving low output voltage rippl...
