Claim 11:
12. A method, comprising:
converting, with a converter, an input voltage potential to an output voltage potential, the input voltage potential and the output voltage potential including direct current (DC) voltage potentials;
generating, by a controller, pulse width modulation (PWM) signals responsive to a duty cycle control signal;
controlling, by the controller, the converter via the PWM signals in a buck mode when the duty cycle control signal is less than a predetermined maximum buck value; and
controlling, by the controller, the converter via the PWM signals in a cascaded buck-boost mode (CBB mode) when the duty cycle control signal is greater than the predetermined maximum buck value; and
transitioning a duty cycle of at least a portion of the PWM signals linearly with the duty cycle control signal from the buck mode to the CBB mode.
