Connected to the front-end AC power grid, it has excellent network adaptability on the power grid side (stable power grid, weak network, micro-network can be applied). Connect the back end electrolyzer to provide continuous adjustable DC voltage and current for the electrolyzer。

Usually, 1000Nm3 electrolyzer is equipped with a hydrogen production power supply of about 5MW, 200Nm3 electrolyzer is equipped with a hydrogen production power supply of 1MW, and so on.

IGBT hydrogen production power supply can convert the AC power into the DC power，suitable for the operation requirements of the electrolyzer. For the AC/DC-DC/DC two-stage topological power supply, the AC/DC rectifiers the AC into fixed DC，and the DC/DC adjusts the fixed DC voltage to the voltage required by the electrolyzer.

Hopewind IGBT hydrogen production power supply adopts non-isolated design, which can be isolated from the power grid through the AC side step-down transformer.

IGBT is a fully controlled device, compared with thyristor power supply, has more advanced technical characteristics: support 10~110% wide power range adjustment, ±10% voltage and frequency adaptability, fast response, especially suitable for green hydrogen production application scenarios; Grid characteristics are good, the grid  harmonic THDi≤3%; Power factor > 0.99.

Hopewind has both liquid-cooled and air-cooled hydrogen power supply, and can choose the optimal solution according to power, environment, installation location, and floor area.
