The disclosure provides an on-board charger control system and method. The on-board charger comprises a rectifier and a CLLC resonant converter connected in series with the rectifier to charge an on-board battery, and the provided on-board charger control method comprises: determining a desired output voltage Vdc_ref for the rectifier based on a detected battery voltage Vdc_out; determining a desired output current Idc_out_ref for the CLLC resonant converter based on the battery voltage Vdc_out; determining a switching frequency f for the CLLC resonant converter based on a voltage gain M and a quality factor Q of the CLLC resonant converter; performing switching control on the rectifier so that the output voltage Vdc of the rectifier is near or equal to the determined desired output voltage Vdc_ref of the rectifier; and performing switching control on the CLLC resonant converter, wherein performing switching control on the CLLC resonant converter comprising performing switching control on the CLLC resonant converter based on the switching frequency f. The on-board charger control method proposed in the disclosure enables an effective all-regime control for the rectifier and CLLC resonant converter.
