具有扩展ZVS范围和高效率的单相单级双向DAB AC-DC变换器

Conventional analyzations on the dual active bridge-based single-phase single-stage ac–dc converter relies on the line-piecewise model with which power switches are viewed as ideal and the commutation process between the top and bottom switch in each bridge leg are ignored. Although many soft-switching have been proposed, the effects of the commutation process make them inaccurate because of the d...
