FIGS. 4A and 4B illustrate two example graphical representations of a process similar to method 300 with respect to the passage of time. In graph 400A, curve 402 represents the cyclic PWM pattern of the oversampling controller. The cycles of pattern 402 have been illustrated herein as alternating between a solid line and a dotted line, to ease in understanding. Thus, the first, third, and fifth cycles of pattern 402 are represented by solid lines, and the second, fourth, and sixth cycles of pattern 402 are represented by dotted lines. Curve 404, on the other hand, represents the cyclic PWM pattern of the steady-state controller. Like pattern 402, the cycles of pattern 404 have been illustrated herein as alternating between a solid line and a dotted line. In both graph 400A and 400B, the horizontal axis represents the passage of time. Thus, times 406-416 represent the times at which an oversampling controller may measure voltage of the system and issue voltage-control commands (e.g., commands to pulse power). However, only times 406, 410, and 414 represent the times at which a steady-state controller may issue voltage-control commands.
