Leakage Inductance - an overview | ScienceDirect Topics leakage inductance of the HF transformer enhances the ZVS range of the dc-ac converter but reduces the duty ratio of the converter, which increases the conduction loss. Thus, the leakage inductance of each transformer is designed to achieve the highest efficiency, as illustrated in Fig. 29.18.For the sinusoidally modulated dc-ac converter, the ZVS capability is lost twice in every line cycle.
