Abstract: One or more converters are selected from a plurality of converters to enable where there is a plurality of energy storage modules electrically connected together in series. Each converter is electrically connected to a corresponding energy storage module. The selected converters are enabled where in response to being enabled, an enabled converter converts an input, from its corresponding energy storage module, at a first voltage level into an output at a second voltage level and the outputs of the enabled converters are electrically combined to produce a combined output. The combined output is compared against a desirable operating region defined by an upper threshold and a lower threshold. In response to the combined output being outside of the desirable operating region, the number of enabled converters is adjusted.
