1. An apparatus, comprising:

  • a first converter module configured to convert a wireless power associated with an electromagnetic wave to a first DC voltage;

    a sensor module configured to monitor the first DC voltage, the sensor module configured to produce an output associated with the first DC voltage; and

    a second converter module configured to convert the first DC voltage to a second DC voltage larger than the first DC voltage, the second converter module configured to be enabled by the output from the sensor module when the first DC voltage is above a first threshold voltage, the second converter module configured to be disabled by the output from the sensor module when the first DC voltage is below a second threshold voltage lower than the first threshold voltage, the second converter module configured to provide power a load device based on the second DC voltage.
