  • Method for controlling on-board charger of eco-friendly vehicle
    Patent number: 9481255
    Abstract: A method for controlling an on-board charger (OBC) of an eco-friendly vehicle can widen the range of an AC input power frequency at which the charging operation of the OBC is possible without increasing the capacity of a power factor correction (PFC) capacitor. According to the method, an increase in output voltage ripple of the PFC capacitor is suppressed by sensing an AC input voltage frequency and then performing variable control of decreasing output power of the OBC based on the sensed frequency, i.e., a variable control of decreasing the output power of the OBC as the AC input voltage frequency decreases, so that the range of the AC input power frequency at which the charging operation of the OBC is possible can be extended without increasing the capacity of a PFC power element.
