METHOD OF SUPPLYING POWER, APPARATUS FOR PERFORMING THE METHOD AND DISPLAY APPARATUS HAVING THE APPARATUS

摘要

PURPOSE: By linearly increasing and decrease the feedback current based on the first voltage applied in the main primary winding of the primary winding of the rectified input voltage and conversion circuit the power supply device for being proceed the method for supplying power, and this and display device including the same can improve the power factor. CONSTITUTION: The alternating current rectifier circuit rectifies the input voltage which it is applied from outside. The conversion circuit(540) comprises the secondary winding which is separated with the primary winding having the main primary winding and the secondary primary winding and is separated with the primary winding.
