QQ-spirakore for power factor correction device, has silicon steel strips or non-crystallized magnetic strips of specific width, where stripes are wound around ball-shaped core whose middle portion is machine-cut into two blocks

摘要

The spirakore (30) has a ball-shaped core including an inner ring, and silicon steel strips or non-crystallized magnetic strips of specific width, where the strips are wound around the core, which includes an inner ring. A middle portion of the core is machine-cut into two blocks such that both the blocks are arranged in a bobbin (20) of a power factor correction device. The edges of the two blocks are curved shaped. An independent claim is also included for a power factor correction device including a QQ-spirakore.
