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.

Transformer - Industrialin transformer is a passive electrical device that transfers electrical energy from one electrical circuit to another, or multiple circuits. A varying current in any one coil of the transformer produces a varying magnetic flux in the transformer's core, which induces a varying electromotive force across any other coils wound around the same core.
Circuit Breakers: Air vs. SF6 Insulated - Electric power ...· The other option is SF6 insulated bus bars and such switchgear is called GIS or Gas Insulated Switchgear (where-in Sf6 gas is employed for busbar insulation and also as interrupting medium in circuit breakers (different pressures). This switchgear is compact and is normally used where the space is a constraint.
