ABSTRACT:
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.
