N2 - In this paper, a novel zero-voltage transition (ZVT) snubber cell is proposed for dual buck full bridge inverter (DBFBI) under full-cycle and half-cycle modulation. Due to the characteristic of auxiliary snubber cell, the soft-switching condition can be realized within continuous conduction mode (CCM) and discontinuous conduction mode (DCM) of inductor current. The important feature of the proposed converter is that the efficiency of the system is improved through the resonant circuit while the high reliability of the converter is maintained. Moreover, the resonant circuit still be effective in two main modulation methods. The soft-switching can transfer the stored energy effectively and ensure the auxiliary circuit in a state of soft-switching. The zero-voltage-transition operation of the proposed converter is presented through theoretical analysis. The characteristics of the ASCDBFBI are verified with the 200k experimental prototype.
