Claim 31:
32. The resonant switching power converter circuit according to claim 8, 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 first inductor between the first power and the second power, and in the second process, the first capacitor and the third capacitor are connected in series with the second inductor and the first inductor respectively, and the series connections are 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 second inductor operate in resonant fashion, and/or, the third capacitor and the first inductor operate in resonant fashion, to achieve power conversion between the first power and the second power.
