  • Publication number: 20240222990
    Abstract: Systems and methods for simultaneously generating a charging signal and a power signal via a converter having a first leg, a second leg, a third leg, and a fourth leg are disclosed herein. An alternating current (AC) source input voltage having a fundamental frequency of a power system is received. The charging signal is generated by the first leg and the second leg and the power signal is generated by the second leg, the third leg, and the fourth leg. The second leg is switched at the fundamental frequency and the first leg, the third leg, and the fourth leg are switched at frequencies higher than the fundamental frequency.

  • Publication number: 20240154534
    Abstract: Systems and methods for controlling a dual active bridge converter are disclosed herein. A bus voltage of a dual active bridge (DAB) converter is detected and a first duty ratio of a primary bridge and a second duty ratio of a secondary bridge are determined, at least one of the first duty ratio and the second duty ratio are modified by adjusting at least one of a differential mode (DM) adjustment variable and a common mode (CM) adjustment variable based on the detected bus voltage. A plurality of switch control signals, which are provided to respective switches of the primary bridge and the secondary bridge, are caused to switch according to a time-based switching sequence based on the first duty ratio and the second duty ratio.
