Abstract
A power control device for an electrolyzer that is configured to encode power curtailment information as a DC bus voltage level using a DC droop characteristic in first stage and decode the DC bus voltage to power information in a second stage.
Claims17
An electrolyzer system, comprising:
- a first stage comprising an AC to DC conversion device and an AC to DC conversion device controller, said AC to DC conversion device controller configured to encode power curtailment information as a DC bus voltage level using a DC droop characteristic;
- and
- a second stage comprising a DC/DC converter and a DC/DC controller, said DC/DC controller configured to decode the DC bus voltage level to power information.
A method of operating an electrolyzer system, comprising:
- encoding power curtailment information as a DC bus voltage level using a DC droop characteristic in a first stage;
- decoding the DC bus voltage level to power information in a second stage;
- converting the DC bus voltage to a variable DC current;
- and
- providing the variable DC current to an electrolyzer stack comprising a group of electrolyzer cells.
