Abstract
Described is a method for converting power including controlling operation of a plurality of series connected modules including a DC power sources and storage devices such that the total voltage across the series connected modules includes an AC signal. A storage parameter is defined based on a sum of a function of the voltages in the storage devices in the modules and one or more voltage control levels are defined for each of or a plurality of the storage devices. An average current drawn from the series connected modules over a time period is set such that the storage parameter approaches a target value. The target value is decreased for a subsequent time period in the event that none the voltage control levels are reached and increased in the event that one or more of the voltage control levels are reached.
