摘要
A device for compensating ripples in the output voltage of a PFC converter and a battery charging device for an electric vehicle are disclosed. The disclosed device for compensating the ripples included in the output voltage of a PFC converter includes: a first switching element having one end connected with an output terminal that is not connected with a ground from among two output terminals forming an output end of the PFC converter; a second switching element having one end connected with the other end of the first switching element and having the other end connected with a ground; a compensation inductor having one end connected with the other end of the first switching element and with one end of the second switching element; and a compensation capacitor having one end connected with the other end of the compensation inductor and having the other end connected with a ground.
