1. A multi-path resonant circuit, comprising: at least two paralleled N-phase resonant circuits, N being an integer greater than or equal to 3; the at least two paralleled N-phase resonant circuits comprising a first N-phase resonant circuit and a second N-phase resonant circuit; a first resonant inductor in any phase resonant circuit of the first N-phase resonant circuit being coupled with a second resonant inductor in any phase resonant circuit of the second N-phase resonant circuit, each resonant inductor is coupled at most once, wherein the at least two N-phase resonant circuits further comprise a third N-phase resonant circuit; a third resonant inductor in any phase resonant circuit of the third N-phase resonant circuit is coupled with a fourth resonant inductor in the first N-phase resonant circuit, or the third resonant inductor is coupled with a fifth resonant inductor in the second N-phase resonant circuit, the third inductor is not coupled to the first or second resonant inductor.
