1. A photovoltaic power generation system including a plurality of integrated photovoltaic modules whose outputs are connected in parallel to a bus, at least one of the integrated photovoltaic modules comprising:

  • a photovoltaic panel configured to generate a first DC voltage at its output; and

    a dc transformer configured to receive the first DC voltage and output a second DC voltage, the dc transformer including;

    a transformer including a primary winding and a secondary winding;

    switching circuitry coupled between the output of the photovoltaic panel and the primary winding of the transformer, the switching circuitry configured to convert the first DC voltage to a first AC voltage at the primary winding of the transformer; and

    rectifier circuitry coupled between the secondary winding and the bus and configured to convert a second AC voltage across the secondary winding to the second DC voltage at the bus.
