  • On-board charger (OBC) having grid frequency rejecter
    Patent number: 11271473
    Abstract: An on-board charger (OBC) for using AC power to charge a traction battery of an electric vehicle includes a DC/DC converter and a controller. The converter receives input power including a voltage having a DC voltage component and a voltage ripple varying at a frequency of the AC power. The controller generates a control signal for controlling the converter to convert the input power into an output power having a current for charging the battery. The controller includes a filter which enhances a sensed value of the current at the frequency to generate a locally-enhanced sensed value of the current. The controller determines a difference between a target and the locally-enhanced sensed value of the current and generates the control signal based on the difference such that the converter in converting the input power into the output power in response to the control signal adapts the current to the target.
