A low cost charger circuit with pre-charge functionality can include a DC/DC converter arranged in parallel with a charger device. When used for electrified vehicle applications, the DC/DC converter can be configured to operate during vehicle propulsion, restorable energy storage system (RESS) recharging, and while only the DC/DC converter needs to be energized. A DC/DC converter can be coupled to a first high voltage bus on a load side of a primary contactor, and to a second high voltage bus on an energy side of a primary contactor. A pre-charge circuit can controllably charge a voltage bus and protect a DC/DC converter against high inrush current. An auxiliary contactor can controllably couple a DC/DC converter to a load portion of a high voltage bus. It can also couple a charger thereto. A charger contactor can controllably couple a charger device to an energy portion of a high voltage bus.
