Abstract
A device for converting electrical power between a PV generator and an electrolyzer. The device has an inverter arranged between a first side thereof and a transformer, and an active rectifier is arranged between the transformer and a second side of the device, such that an AC side of the active rectifier and an AC side of the inverter are connected to one another via the transformer. The inverter is configured to convert a first DC voltage on the DC side of the inverter into a first AC voltage on the AC side of the inverter and the active rectifier is configured designed to convert a second AC voltage on the AC side of the active rectifier into a second DC voltage on the DC side of the active rectifier. The device has a controller configured to influence a power flow between the first side and the second side of the device from a connected PV generator to a connected electrolyzer by adjusting an AC/DC transformation ratio of the active rectifier between the second AC voltage and the second DC voltage.
