The present invention provides a charging system and a method thereof for an environmentally friendly vehicle, which commonly uses a capacitor respectively used for an inverter and an on-board charger (OBC), connects an output end in the OBC in between a main relay and a high-voltage battery, lets the inverter and the OBC commonly use the capacitor placed in the inverter, increases the charging efficiency of the OBC, reduces excessive use of capacitors, and decreases the cost price of parts. According to an embodiment of the present invention, the on-board charging system for a hybrid vehicle is connected to an output relay of an OBC connected in between a high-voltage battery and a main relay, a DC/DC converter connected in between the main relay and the inverter, and a PFC module of the inverter and the OBC, and lets the OBC and the inverter commonly use the capacitor of the inverter. |
