Abstract
A display apparatus includes: a display, a processor configured to process image data to be displayed on the display, a transformer including a primary coil and a plurality of secondary coils, a first rectifier connected with a first coil of the plurality of secondary coils and configured to output a first output voltage corresponding to a number of turns of the first coil, a direct current-direct current (DC-DC) converter configured to receive the first output voltage from the first rectifier and output a second output voltage that is different from the first output voltage, and a second rectifier connected with a second coil of the plurality of secondary coils and configured to output a first load voltage which is a sum of the second output voltage and a third output voltage corresponding to a number of turns of the second coil to the display.
