ABSTRACT:
A compact multiple output switching power supply having a series connection of a D.C. input power supply, a switching device and a primary winding of a transformer which supplies currents to loads during an on period of the switching device, and supplies constant output voltages V.sub.i (i=1, 2, . . . , m) from m (m.gtoreq.2) secondary windings n.sub.i (i=1,2, . . . , m) of the transformer by turning on and off the switching device, includes means for storing a magnetic energy during the on period of the switching device and discharging the stored energy to the loads during on off period, connected in series with the primary winding of the transformer. The output voltage V.sub.j (j=2, 3, . . . , m) is represented by
