| 摘要 |
<p>A photovoltaic (PV) inverter system (100) operates continuously in a buck converter mode to generate a sum of full wave rectified sine wave currents at a current node common to a plurality of buck converters in response to a plurality of full wave rectified sine wave currents (120), (122), (124), (126) generated via the plurality of buck converters. The PV inverter system (100) increases the level of the voltage sourcing each buck converter when a corresponding DC power source voltage (104), (106), (108), (110) is lower than the instantaneous voltage of a utility grid connected to the PV inverter system (100).</p> |
