In the resonant switching power converter circuit shown in the figure, the primary windings of inductors L1 and L2, together with capacitor C1, form two resonant circuits. The secondary windings of L1S and L2S serve as flyback windings to deliver energy to the load. Multiple switching transistors Q1-Q4, driven by external pulses, serve as a switch to develop the resonant currents through L1P and L2P. Transformer T1 provides current feedback for Q1-Q4.
