FLAT TRANSFORMER FOR HIGH FREQUENCY

摘要

PURPOSE: A high frequency flat transformer is provided to provide effect capable of improving illumination properties by providing the LED driver of high power density. CONSTITUTION: At least one magnetic core(110a,110b) is formed in a ring shape having a hollow inside. A first side winding coil(200) passes through one or more magnetic cores consecutively. At least one second side winding coil(300a,300b) passes through any one magnetic core of one or more magnetic cores. The number of the magnetic cores and the turn number of a first side winding coil are designed to be inversely proportional. The magnetic core applies a ferrite core for high frequency.
