Good quality Toroidal Coil Inductance - 220 To 110 High Frequency Flyback PQ32 Ferrite Core PFC Inductor – Sanhe
Good quality Toroidal Coil Inductance - 220 To 110 High Frequency Flyback PQ32 Ferrite Core PFC Inductor – Sanhe Detail:
Introduction
It is mainly used in the primary input part of LLC resonant circuit. As the power of the laser power supply is rather large, it is necessary to modify power factor to synchronize curves of voltage input and current input as much as possible and to reduce the loss caused by reactive current in circuits. Working efficiency of the power supply also has been improved. Because the inductor works in high frequency condition, interferences such as electromagnetic radiation easily appear. It is necessary to take shielding measures to avoid excess of EMC by standard.
