Method and inverter for distributing power to a plurality of DC power sources commonly connected to a DC voltage input of a DC-AC converter

摘要

In order to distribute power to a plurality of DC power sources (25) connected in parallel to the input side DC voltage intermediate circuit (5) of the DC / AC converter (6), at least one of these DC power sources (25) It is connected to the DC voltage intermediate circuit (5) via the DC / DC converter (2), and is supplied to the DC voltage intermediate circuit (5) by the DC power supply (25) by operating the DC / DC converter (2). The power level of the DC power supply (25) is reduced separately in the reduced operation mode of the DC / AC converter (6), and the power of the DC / AC converter (6) is all And at least one DC / DC converter (at least one DC power source (25) connected to the DC voltage intermediate circuit (5)). ) By operating a variation of the power level of at least one other of the DC power supply (25) is dynamically compensated.
