Abstract
A system includes four primary-side switches of a primary bridge of a dual active bridge (DAB) converter, four secondary-side switches of a secondary bridge of the DAB converter, and control circuitry configured to operate the DAB converter in a first mode, where all of the four secondary-side switches operate under zero voltage switching (ZVS) and less than all of the four primary-side switches operate under ZVS, and, in response to a thermal condition, operate the DAB converter in a second mode, where less than all of the four secondary-side switches operate under ZVS and all of the four primary-side switches operate under ZVS. A method includes operating the control circuitry of the system to implement the first and second modes. In some embodiments, the control circuitry toggles between the first and second modes based on one or more thermal conditions.
