<p>PROBLEM TO BE SOLVED: To provide a transformer in which occurrence probability of a high pot is lowered between a primary coil and a secondary coil, by having a flux loop of high permeability, and enhancing the withstand voltage strength of the whole transformer, without up-sizing a core around which each coil is wound.SOLUTION: A transformer includes a first magnetically permeable element 11, a primary coil C1, a secondary coil C2, and a second magnetically permeable element 12. The primary coil is installed while being wound around the first magnetically permeable element. The secondary coil is also installed while being wound around the first magnetically permeable element. The second magnetically permeable element includes a first protrusion edge P1 and a second protrusion edge P2. The first protrusion edge is installed at one end of the second magnetically permeable element, and the second protrusion edge is installed at the other end of the second magnetically permeable element. The first and second protrusion edges are connected with the first magnetically permeable element, and permeability of the second magnetically permeable element is higher than that of the first magnetically permeable element.</p> |
