1. A receiver comprising:

  • an antenna configured to convert received radio frequency (RF) waves into an alternating current (AC) voltage;

    a rectifier coupled to the antenna, wherein the rectifier is configured to rectify the AC voltage into a first direct current (DC) voltage;

    a first boost converter, distinct from the rectifier, that is coupled to the rectifier, wherein;

    the rectifier is electrically positioned between the antenna and the first boost converter; and

    the first boost converter is configured to boost the first DC voltage from the rectifier to a second DC voltage that is greater than the first DC voltage;

    a charger coupled to the first boost converter, wherein the charger is configured to;

    receive the second DC voltage from the first boost converter; and

    control, via circuitry included in the charger, distribution of voltage using a plurality of conduction paths (i) to a load and (ii) to and from at least one storage element coupled with the charger, wherein the circuitry controls distribution of the second DC voltage to the at least one storage element based at least in part on an operational characteristic of the at least one storage element; and

    a second boost converter, distinct from the rectifier, coupled to the charger, wherein;

    the charger is electrically positioned between the first boost converter and the second boost converter, andthe second boost converter is configured to boost the second DC voltage from the charger to a third DC voltage, greater than the second DC voltage, that matches at least one of an impedance and a power requirement for the load.
