Abstract
To optimize the current stress of a single-stage DAB DC/AC converter, the DAB topology is improved with an additional switch. The current stress is effectively reduced by actively changing the structure between half and full bridge. The operation mode, current stress analysis, and simulation results are shown in detail.
