Abstract
The present invention aims to prevent magnetic flux from leaking towards the outer side of an inverter transformer. The disclosed inverter transformer (10), comprising coil bobbins (12a, 12b) wound after the separation of a primary winding and a secondary winding from a same axis and a pair of magnetic cores (24a, 24b) having core pins (24f, 24g, 24h), steps up or down an alternating voltage inputted from the primary side before outputting the alternating voltage towards the secondary side, where two of the core pins (24f, 24g) are inserted into the coil bobbins (12a, 12b) to connect with the pair of magnetic cores (24a, 24b), respectively, so that the pair of connected magnetic cores (24a, 24b) form a closure magnetic circuit connected with the coil bobbins (12a, 12b).
