Graph 200B in FIG. 2B illustrates the timeline of graph 200A as applied to two converters (i.e., as applied to the two converters by the pulse commands from a voltage controller) in a two-converter system. Indicator line 218 represents the current delivered by the first converter, and indicator line 220 represents the current delivered by the second converter. For example, where indicator line 218 is low (e.g., as displayed immediately before time 206), the first converter is not pulsing current. However, where indicator line 218 is high (e.g., as displayed immediately after time 206), the first converter is pulsing.
