Abstract
An inverter transformer in which to overall structure and manufacturing process can be simplified despite its closed magnetic path structure, and a cost increase can be suppressed. Primary windings (,,) and secondary windings (,,) wound around a plurality of rod-like cores (,,) have leakage inductances. The primary windings (,,) axe wound around respective rod-like cores (,,) such that magnetic fluxes being induced in respective cores by the currents flowing through the primary windings (,,) are directed reversely to magnetic fluxes being induced in adjacent cores.
