The Hydrogen Electrolysis Rectifier is a DC power supply device used to produce hydrogen by electrolyzing water. It converts AC power into DC power to provide the required electrical energy for the electrolyzer, thereby decomposing water molecules to produce hydrogen and oxygen. This type of equipment is essential for achieving green energy transformation and hydrogen economy.
*Photovoltaic, wind power, wave power, biomass power(green power) are connected to the power sourcerectifier and the electrolyzer to electrolyze hydrogen production
*Electrolytic hydrogen production by power source rectifer connected to conventional power grid and integrated with electrolyzer
*Inverter system between hydrogen energy storage and power grid
*Select the core device thyristor with low on-state threshold voltage to reduce losses, improve efficiency and achieve stable overall performance;
*The number of parallel components of the bridge arm is controlled within a reasonable range,improve the current sharing coefficient of the rectifier bridge arm;
*Self-developed low-power current-sharing reactor to improve the efficiency
*Stable, safe, decades of technology, output voltage up to 1500V, current 100kA(or special customization);
*Multi-pulse modes such as 12, 24, and 36 can be used to reduce the impact of power supply system on power grid.
