Abstract :
In the present paper the small-signal model of the half-bridge soft-switched single active bridge is derived. In order to derive the small-signal model of the specific topology an extended state-space averaging method based on half-cycle symmetry has been used and is briefly described in the paper. The results obtained have been verified experimentally.
