The inputs and outputs of the converters 3170, 3172, and 3276 are shown as individual links for a given direction of power. However, this is a functional visualization only, and does not represent specific physical implementations. In some cases, a single I/O can couple the converters 3170, 3172, and 3276 to the bus 3060. In some cases, a single I/O can couple the converters 3170, 3172, and 3276 to the energy storage device 3108, 3208. In other embodiments, two or more physical leads can be used in the I/O interfaces to the bus 3060 and/or the energy storage device 3108, 3208.
While specific voltage and current sensing channels have been shown, in some embodiments, additional channels may be implemented, for instance, where a power measurement as compared to a mere voltage measurement, is desired.
