Abstract (en)
A power factor corrector uses a design of a film-like QQ-type spirakore to largely reduce a waste of material and to effectively reduce ill products. The magnetic crystal generated is a non-orientation structure, and the egg-shape spirakore is a structure without angles, which facilitate a guidance of air flow, thereby having a better effect of heat dissipating and reducing an unusual tone and low frequency ripple interference. Moreover, each wire bundle in the coil structure is configured by merging thick and thin coils, and the thick and thin coils are interleaved between each wire bundle, which can effective reduce interference of magnetic lines of force between the coils and reduce the magnetic leakage, thereby acquiring a better effect of inductance.
