COIL STRUCTURE AND ELECTRIC POWER CONVERSION DEVICE

摘要

Disclosed is a coil structure including: a first wire rod including a first coil portion and a first lead wire connected to the first coil portion, the first coil portion winding around a coil axis in a first space; a second wire rod including a second coil portion, the second coil portion winding around the coil axis in a second space, the second space being aligned with the first space along the coil axis; and an insulating structure including a first insulating section that insulates the first coil portion from the second coil portion. The first lead wire portion extends through the second space. The insulating structure fixes the first lead wire portion at a position that is away from the second coil portion by not less than a minimum creepage distance between the first and second coil portions, the minimum creepage distance being defined by the first insulating section.
