A direct current (DC) boost charging (DCBC) system for a high voltage (HV) battery system of an electrified vehicle includes a charging module including (i) an isolated DC-DC converter connected to the HV battery system, (ii) bypass switches connected to the HV battery system and in parallel with the DC-DC converter, and (iii) a power factor correction (PFC) module connected between (a) an input DC voltage and (b) the DC-DC converter and the bypass switches, and a controller configured to command the PFC module to boost the input DC voltage to a higher DC voltage appropriate for recharging the HV battery system, and command the bypass switches to temporarily close thereby bypassing the DC-DC converter for recharging the HV battery system using the higher DC voltage generated by the PFC module.
