    摘要： A photovoltaic unit is disclosed comprising a plurality of sub-units connected in series, each sub-unit having a main input and a main output, which main output is connected to the respective main input of a neighbouring sub-unit, each sub-unit further comprising a segment comprising one or more series-connected solar cells, and a supplementary power unit, wherein the supplementary power unit is configured to at least one of receive power from or supply power to the neighbouring sub-unit. The supplementary power unit is preferably a DC-DC converter, and arranged to exchange energy between neighbouring segments, without requiring a high-voltage connection across the complete string (of more than 2 segments). The converter may be inductive or capacitive.
    A DC-DC converter configured for use in such a unit is also disclosed, as is a method of controlling such a photovoltaic unit.

    摘要： A method of performing a service scan for available channels across a bandwidth of an input signal, the method comprising the steps of: acquiring (401) a power spectrum of the input signal bandwidth; analysing (402) the power spectrum to identify a list of candidate channels, each candidate channel being identified by at least a centre frequency; processing (404, 405) each of the candidate channels in a receiver unit (205, 305) to extract (405) service information, if present, relating to the candidate channel; and storing (406) the service information for the channel in a memory (204, 304).
