Claim 30:
31. The resonant switching power converter circuit according to claim 8, wherein one same single inductor serves as the at least one first inductor and the at least one second inductor; wherein in a three-fold conversion mode, a portion of the plurality of switches are always ON, another portion of the plurality of switches are always OFF, and a further other portion of the plurality of switches are configured to switch the first capacitor and the third capacitor so that in the first process, the first capacitor and the third capacitor are connected in series with the one same single inductor between the first power and the second power, and in the second process, the first capacitor and the third capacitor are connected in parallel and the parallel connection is connected in series with the one same single inductor, and the series connection is connected in parallel with the second power, such that a ratio between the first voltage of the first power and the second voltage of the second power is 3, wherein the first capacitor and the one same single inductor operate in resonant fashion, and/or, the third capacitor and the one same single inductor operate in resonant fashion, to achieve power conversion between the first power and the second power.
