1. A method of delivering power to a load coupled to an energy module, the method comprising:
determining, by a controller, the power to be produced for the load coupled to the controller, wherein the load is defined by a surgical instrument coupled to the energy module;
generating, by the controller, a waveform having a predetermined wave shape and frequency based on the load coupled to an output of a first power amplifier circuit or a second power amplifier circuit;
selecting, by the controller, either the first or second amplifier circuit based on the power to be produced for the load;
limiting, by the controller, current, power, and voltage of the waveform based on impedance of the load coupled to the output of the first or second power amplifier circuit; and
wherein a power rating of the first amplifier circuit is different from a power rating of the second amplifier circuit.
