Abstract
Direct current to direct current (DC-DC) boosting and fast charging techniques for an electrified vehicle include providing relay switches electrically connected between a DC charging station rated at a first voltage, an inverter, and a high voltage (HV) battery system rated at a higher second voltage, wherein at least one of the plurality of relay switches is connected to a midpoint of one of three inductor phase legs of the inverter and controlling a boosted fast charging mode wherein the plurality of relay switches are opened/closed such that the first voltage is provided to the inverter and to the HV battery system for recharging, wherein the inverter and the electric motor utilize a first alternating current (AC) phase current based on the first voltage to inductively generate and convert two AC phase currents to a third DC voltage for further boosted recharging of the HV battery system.
