Zusammenfassung:	A method for starting an electrolysis system is disclosed. A supply circuit has an AC terminal connected to an AC grid, a DC terminal connected to an electrolyzer, and an AC/DC converter arranged between the AC terminal and the DC terminal. The method includes charging an output capacitor connected to a DC converter terminal of the AC/DC converter, by operating the electrolyzer in a reverse mode, while the AC/DC converter is connected to the electrolyzer and disconnected from the AC grid, connecting the AC/DC converter to the AC grid, reversing the operation of the electrolyzer from the reverse mode to a normal mode as a DC load, to suppress a power flow between the AC grid and the electrolyzer, and operating the electrolyzer in the normal mode with electrical power drawn from the AC grid which is rectified by the AC/DC converter.
