1. a resonance power converter, is characterized in that it comprises:

  • A pulse input source for generation of a plurality of pulses;

    A resonator, is operatively coupled with aforementioned pulse input source and has or substantially close resonance frequency identical with carrier frequency Fc;

    A load impedance, with an output function of aforementioned resonator be coupled and be applicable to transmit a plurality of radiofrequency signals;

    Wherein, pulse input source comprises;

    One can be with clock rate Fc/L1 receiving digital data the noise reformation encoder to described digital data coding, and wherein, L1 is the multiple of carrier frequency Fc;

    AndA charge switch, can from noise reform encoder received code data;

    Extract a current sample or a voltage sample of frequency power supply identical or approaching with direct current;

    And aforementioned power source sample is transferred to aforementioned resonator.
