摘要： A direct current (DC) to DC converter is provided. The DC to DC converter includes: a transformer which comprises a primary winding which is connected in series with an input voltage and a secondary winding which generates induced current when the input voltage is applied to the primary winding; a switching part which is connected to the primary winding and performs a switching operation according to a predetermined control signal; a first delay part which delays an increasing rate of voltage between open nodes according to a turned-off state of the switching part and supplies a discharge current when the switching part is turned-on; and a second delay part which delays current flow in the switching part when the first delay part discharges the current when the switching part is turned-on.

摘要： A power supply apparatus and display apparatus having the same are provided for outputting power, in which a standby mode selecting unit switches on and off a standby mode, a standby power supplying unit outputs standby power of a predetermined magnitude in the standby mode and temporarily outputs first auxiliary power when the standby mode is released by selecting of the standby mode selecting unit, a main power supplying unit outputs main power of a predetermined magnitude, and a backup power supplying unit continues to supply second auxiliary power, which is induced by the main power output from the main power supplying unit, to the main power supplying unit as driving power substituting the first auxiliary power. Thus, the output of standby power is increased when a standby mode is released, without increasing power consumption in the standby mode, using a standby power converter with small capacity.
