Transformer and display device using the same

Abstract

There is provided a transformer having a minimized leakage inductance. The transformer includes: a bobbin including a plurality of partitioned spaces; and a plurality of coils wound and stacked in the plurality of partitioned spaces, wherein the respective coils are wound so as to be disposed in the plurality of partitioned spaces, and at least one of the coils is a multi-insulated coil.

Description

[0001] This application claims priority from Korean Patent Application No. 10-2011-0057276 filed with the Korean Intellectual Property Office on Jun. 14, 2011, the disclosure of which is hereby incorporated by reference. technical field [0002] The present invention relates to a transformer, and more particularly, to a transformer with minimized leakage inductance. Background technique [0003] Various power sources are required in various electronic devices such as televisions (TVs), monitors, personal computers (PCs), office automation (OA) devices. Therefore, these electronic devices generally include a power source that converts alternating current (AC) power supplied from the outside into power required by each electronic device. [0004] Among power supplies, a power supply utilizing a switch mode (for example, a switch mode power supply (SMPS)) is mainly used these days. SMPS basically consists of switching transformers. [0005] The switching transformer generally...
