1. A wireless power receiver comprising:

  • a controller coupled with a comparator;

    a rectifier coupled to an antenna of the wireless power receiver, the rectifier being configured to rectify energy from wireless power transmission waves received by the antenna into a first voltage;

    a boost converter coupled to the rectifier, the boost converter being configured to increase the first voltage to a second voltage based on instructions from the controller; and

    the controller configured to control an amount of increase in voltage from the first voltage to the second voltage based on a comparison, performed by the comparator, of the first voltage with a reference voltage generated by the controller.
