Abstract
A rectifier circuit applied in an AC/AC power supply, the rectifier circuit including: a filter circuit configured to receive a DC pulsating voltage, and to generate a supply voltage, where the supply voltage follows the DC pulsating voltage during a first time interval of an operation cycle; and where during a second time interval of the operation cycle, a value of the supply voltage is greater than the value of the supply voltage at an end of the first time interval, in order to reduce a size of the filter circuit.
