Abstract
Provided are a method for and a power supply system for a plurality of electrolyzers that includes main input terminals to be connected to a grid, an AC/AC power converter, a control circuit, a plurality of supply branches, each having a branch transformer that includes a primary circuit connected to input terminals of each supply branch and at least one secondary circuit, and at least one rectifier connected to the secondary circuit of the branch transformer, the rectifier having output terminals connected to a set of output terminals of each supply branch to supply the output terminals of each supply branch with a DC current.
Claims15
A power supply system for a plurality of electrolyzers, characterized in that the power supply system comprises:
- main input terminals to be connected to a grid,
- an AC/AC power converter comprising input terminals connected to the main input terminals and output terminals,
- a control circuit configured to control the AC/AC power converter so that an amplitude of at least one supply current delivered in the output terminals by the AC/AC power converter from power supplied by the grid is equal to a predetermined value,
- a plurality of supply branches, each supply branch comprising input terminals and at least one set of output terminals intended to be connected to an electrolyzer,
- the input terminals of the plurality of supply branches being connected in series to the output terminals of the AC/AC power converter to be supplied with the supply current, and
- each supply branch comprising a branch transformer including a primary circuit connected to the input terminals of the said supply branch and at least one secondary circuit, and at least one rectifier connected to the secondary circuit of the branch transformer, the rectifier comprising output terminals connected to the set of output terminals of the said supply branch to supply the output terminals of the said supply branch with a DC current.
A method for supplying a plurality of electrolyzers, the method comprises:
- controlling an AC/AC power converter comprising input terminals connected to main input terminals coupled to a grid, and output terminals so that the amplitude of at least one supply current delivered in the output terminals by the AC/AC power converter from power supplied by the grid is equal to a predetermined value
- supplying input terminals of a plurality of supply branches connected in series to the output terminals of the AC/AC power converter with the supply current,
- each supply branch comprising at least one set of output terminals connected to an electrolyzer, a branch transformer including a primary circuit connected to the input terminals of the said supply branch and at least one secondary circuit, and at least one rectifier connected to the secondary circuit of the branch transformer, the rectifier comprising output terminals connected to the set of output terminals of the said supply branch, the rectifier supplying the set of output terminals of the said supply branch with a DC current to supply the said electrolyzer.
