ABSTRACT:
The switching power supply apparatus of the present invention comprises first and second switching units connected to a DC power source and connected to each other serially, third and fourth switching units connected to the DC power source and connected to each other serially, and a transformer including a primary winding connected to between a connecting point between the first and second switching units and a connecting point between the third and fourth switching units, wherein the first and second switching units is controlled so that the first and second switching units are in an ON-state complementarily after a first predetermined dead time period in which both of the first and second switching units are in an OFF-state, the third and fourth switching units is controlled so that the third and fourth switching units are in the ON-state complementarily after a second predetermined dead time period in which both of the third and fourth switching units are in the OFF-state, and the first through fourth switching units are controlled so that a short-circuited time in which the primary winding is short-circuited is set between the first and second dead time periods.
