Claim 14:
15. The resonant switching power converter circuit according to claim 1, further comprising an upper layer capacitor and a plurality of upper layer switches, wherein the at least one switching converter includes a first switching converter and a second switching converter, wherein the upper layer capacitor, the plurality of upper layer switches, the first switching converter and the second switching converter are coupled with one another to form a fundamental topology;
wherein in the first process, the plurality of upper layer switches further control the first switching converter and the upper layer capacitor to be connected in series with each other between the first power and the second power, and control the second switching converter to be connected in parallel with the second power; and
wherein in the second process, the plurality of upper layer switches further control the second switching converter and the upper layer capacitor to be connected in series with each other between the second power and the ground level, and control the first switching converter to be connected in parallel with the second power.
