Abstract:
A low-loss choke structure with no air gap includes a magnetic core unit, a coil and an insulator. The magnetic core unit has two magnetic cores. Each of the magnetic cores has a post. The coil has a wired portion. The wired portion has an input end and an output end. The two posts of the magnetic cores are respectively inserted into opposite sides of the wired portion and each have an end face contacting each other. The input end and the output end both are inserted into the insulator, which is arranged below the magnetic cores. There is no air gap between the two end faces of the two posts, thus lowering the eddy current loss, suppressing the noise generation, decreasing cost and size, and providing improved DC bias characteristics.
