Claims

[Claims for Utility Model Registration] (1) A gap 12 is provided in the core 11, which is a chain through which a current including a direct current component flows through the winding 14 and forms a magnetic circuit, and both ends 11a of the core sandwiching the gap 12, A magnetically biased cheese yoke is provided with a permanent magnet 13 located on the side of the gap 12 astride the gap 11b. (2) A transformer in which a current including a direct current component flows through the primary winding 31, in which a gap 12 is provided in the core 11 forming a magnetic circuit, and the core ends 11a and 11b sandwiching the gap 12 are straddled. A magnetically biased transformer is provided with a permanent magnet 13 located on the side of the gap 12.
