Abstract
At least one example embodiment discloses a method of generating an output variable voltage. The method includes obtaining a selected mode of operation, the selected mode of operation being one of an voltage control mode and a frequency mode, determining an input voltage command based on the selected mode of operation, determining an input frequency command based on the selected mode of operation, adjusting at least one of the input frequency command and the input voltage command based on the selected mode of operation, generating a pulse width modulation reference based on the adjusted at least one of the input frequency command and the input voltage command and generating the output variable voltage based on the pulse width modulation reference.
