1. A system comprising:
one or more processors; and
one or more computer-readable media storing instructions executable by the one or more processors, wherein the instructions, when executed, cause the system to perform operations comprising:
receiving a signal that a vehicle is in position with respect to a wireless charging coil;
receiving a first current request;
controlling, based on the first current request, a plurality of transistors in a control circuit associated with a bipolar mode;
controlling, based on individual first states of corresponding transistors in the plurality of transistors, an inverter to output a first square wave signal and a first duty signal, the first square wave signal being utilized to transmit power at a first power level from a power converter;
receiving a second current request;
controlling, based on the second current request, the plurality of transistors in the control circuit associated with a unipolar mode; and
controlling, based on individual second states of corresponding transistors in the plurality of transistors, the inverter to output a second square wave signal and a second duty signal.
