1. An apparatus of a wireless power transfer system, comprising:
a secondary coil configured to receive wireless power from a primary coil associated with a first converting unit, the wireless power having an alternating current (AC) voltage;
a second converting unit comprising a first plurality of circuit elements configured to convert the wireless power from the AC voltage to an output direct current (DC) voltage and provide the output DC voltage to an electric load;
a first transceiver configured to communicate a voltage signal representative of the output DC voltage across the electric load, wherein the voltage signal is configured to cause the first converting unit to adjust the AC voltage of the wireless power based on the output DC voltage across the electric load; and
a switching unit electrically coupled to the second converting unit, the switching unit comprising a second plurality of circuit elements configured to regulate the output DC voltage when the output DC voltage across the electric load is greater than a voltage reference value.
