A switching power supply circuit according to the embodiment, which includes a switching unit having at least one switch and connected to one side of a transformer, includes a switching controller connected to an output side of the switching unit for controlling the switching unit based on an output of the switching unit, wherein the switching controller includes a comparing unit and an output waveform generating unit. According to the embodiment, the power consumption is reduced by performing rectification using a switch, and since the switching unit is controlled without any controller, the switching power supply circuit is prepared in a simple configuration. |
