摘要： Controlling reverse in-rush current for vehicle chargers is provided. A system can include a controller to determine a first value of voltage. The voltage can be of or associated with a DC link of a charger to output power to a battery of an electric vehicle. The controller can detect an in-rush current from the battery to the charger. The detection can be responsive to the first value of voltage at the DC link being greater than a reference value of voltage established for the DC link.

摘要： Current sensor compensation is provided. A system can include a charger for an electric vehicle having one or more controllers. A controller can amplify an input signal at a selected frequency to generate a first signal. A controller can amplify a direct current component of the input signal to generate a second signal. A component of the charger can generate a reference signal for input into a current sensor of the charger. The reference signal can be based on a combination of the first signal and the second signal.

摘要： Systems and methods for controlling a dual active bridge converter are disclosed herein. An output voltage of a dual active bridge converter is sensed. Based at least in part on the output voltage, a target intra-bridge phase shift amount between two bridges of the dual active bridge converter is computed. A plurality of switch control signals, which are provided to respective switches of the dual active bridge converter, are caused to switch according to a time-based switching sequence based on the target intra-bridge phase shift amount to compensate for variations in the output voltage.

摘要： Various disclosed embodiments include illustrative controller modules, direct current (DC) fast charging devices, and methods. In an illustrative embodiment, a controller module for a DC-DC converter includes a controller and computer-readable media configured to store computer-executable instructions configured to cause the controller to: receive an input voltage, an output voltage, and a requested power value. The computer-executable instructions are configured to cause the controller to: determine primary and secondary side inter-bridge phase shifts responsive to the requested power value, the input voltage, and the output voltage; determine an effective phase shift value responsive to the requested power value, the input voltage, the output voltage, and the primary side inter-bridge phase shift; generate control signals for switches of the DC-DC converter responsive to the primary side inter-bridge phase shift, the secondary side inter-bridge phase shift, and the effective phase shift value; and output the generated control signals.
