Abstract
A system and method of operation which includes a variable transformer coupled to an invariable rectifier, an invariable inverter, and/or other invariable change component. The variable transformer may be used to control power conversion levels. In some cases, the system may have bandwidth to support controlled power supply for one or more electrolyzer stacks.
Claims11
A power converter device, including:
- a first port;
- a second port coupled to one or more electrolyzer stacks;
- multiple variable transformers that are phase-shifted relative to one another to implement a harmonic cancellation effect, the multiple variable transformers coupled to the first port;
- and
- an invariable rectifier coupled between the multiple variable transformers and the second port,
- wherein the power converter device is configured to convert alternating current (AC) power at the first port to direct current (DC) power at second port, and
- wherein the invariable rectifier is configured to operate without power regulation input to the invariable rectifier.
4 more elements
A method including:
- converting alternating current (AC) power from an AC power source to be provided as direct current (DC) to one or more electrolyzer stacks by:
- transferring, via multiple variable transformers, the AC power from the AC power source to an output of the variable transformer, wherein the multiple variable transformers are phase-shifted relative to one another to implement a harmonic cancellation effect;
- controlling the variable transformer to control power conversion output of the variable transformer;
- and
- rectifying the AC power at the output of the variable transformer using an invariable rectifier,
- wherein the invariable rectifier is configured to operate without power regulation input to the invariable rectifier.
