  • Publication number: 20230140308
    Abstract: The proposed solution allows a forward DC-DC converter's isolated transformer to resonant reset and the forward DC-DC converter to operate in ZVS condition regardless of whether the output inductor current is in DCM or CCM. To compare with a regular forward DC-DC converter, the output isolated transformer has an extra reset winding Nt in addition to the regular primary and secondary windings Np and Ns. Based on the rule of the magnetic flux remaining unchanged for the forward output isolated transformer, it is the extra reset winding Nt, a resonant capacitor Cr, an additional MOS Q2 and the related control function block M that allow the forward output isolated transformer to finish resonant reset and the primary main power MOS Q1 to operate in ZVS.
