PROBLEM TO BE SOLVED: To provide a switching power supply which is suitable for large current output and reduces cost.SOLUTION: The switching power supply includes a switching transformer T1 having an input-side winding L1 and output-side windings L2 and L3 and fast recovery diodes FRD1 and FRD2. One ends of the output-side winding L2 and L3 are connected in common. Voltages Vand Vgenerated in the output-side windings L2 and L3 have the same polarities with one ends of the output-side winding L2 and L3 as a reference. Other ends of the output-side windings L2 and L3 are connected to respective anodes of the fast recovery diodes FRD1 and FRD2 by one-to-one correspondence, and cathodes of the fast recovery diodes FRD1 and FRD2 are connected in common in the switching power supply. |
