ALTERNATING CURRENT-DIRECT CURRENT CONVERSION CIRCUIT, ALTERNATING CURRENT-DIRECT CURRENT CONVERSION METHOD AND CHARGER

摘要

An AC-DC conversion circuit can include an adaptive rectifier configured to receive an AC input voltage with different ranges, where operation states of the adaptive rectifier are adjusted according to a range of the AC input voltage, in order to decrease a fluctuation range of a DC output voltage of the adaptive rectifier.
