Abstract
The disclosure provides a method and a system for warming-up an electrolytic capacitor. The method comprises: providing a power factor correction circuit comprising an AC terminal, a DC terminal and the electrolytic capacitor, wherein the DC terminal is connected in parallel to the electrolytic capacitor; determining whether it is necessary to perform a warm-up operation on the electrolytic capacitor; when it is determined to be necessary, generating a ripple current on the electrolytic capacitor by controlling an input current to flow into the AC terminal of the power factor correction circuit; and when the warmed-up state of the power factor correction circuit that is generated based on the ripple current matches a specified warmed-up exit condition, terminating the warm-up operation performed on the electrolytic capacitor.
