The present invention relates to a method to control the charging of a charger for an eco-friendly vehicle and, more specifically, to a method to control the charging of a charger for an eco-friendly vehicle, capable of widening a chargeable AC input power frequency range of a charger (OBC) without an increase in a capacity of a PFC capacitor. Variable control is performed to reduce output power of the charger (OBC) according to the sensed AC input voltage frequency but the variable control is performed to reduce the output power of the charger (OBC) as the AC input voltage frequency decreases in order to suppress a rise of a PFC capacitor output voltage ripple, and therefore, the present invention is capable of expanding a chargeable AC input power frequency range of the charger without an increase in a capacity of a PFC power element. |
