Methods, devices, and systems are provided for a power generator system. The power generator system may include at least one control device including control logic. The at least one control device may be configured to receive at least one control signal and output an upper reference voltage and a lower reference voltage. The at least one control device may be further configured to vary a magnitude of at least one of the upper reference voltage and the lower reference voltage. The power generator system may also include a power generator operably coupled to the at least one control device and configured to receive the upper reference voltage and the lower reference voltage. The power generator may be further configured to output a voltage that is greater than or equal to the lower reference voltage and less than or equal to the upper reference voltage.
