Abstract:
Methods and apparatuses for equalizing voltages across a plurality of photovoltaic units connected in series are provided. The apparatus may include a plurality of energy storage devices. In a first configuration, each of the energy storage devices is configured to be connected in parallel with one of a first set of the photovoltaic units, and a voltage across a first one of the energy storage devices has a first polarity. In a second configuration, each of the energy storage devices is configured to be connected in parallel with one of a second set of the photovoltaic units, and the voltage across the first one of the energy storage devices has a second polarity that is different from the first polarity. The apparatus may also include a plurality of switches configured to switch between the first configuration and the second configuration, to equalize the voltages across the photovoltaic units.
