According to the customer’s requirements, they needed a rectifier for water-electrolytic hydrogen production equipment. A common water electrolysis process involves filling a stack of catalytic cells with electrolytic water and extracting hydrogen through an electrical chemical reaction. The catalysts are connected to a power source to decompose water into oxygen and hydrogen gas and are typically made from expensive metals such as platinum or iridium.

The TB series synchronous rectifier power supply, independently developed by Liyuan, offers high energy efficiency and stable output performance. It is built using the latest generation of energy-saving high-frequency MOSFET switching power supply technology, including synchronous rectifier MOSFETs imported from the United States. Its voltage drop is only 0.1V, 0.6V lower than ordinary second-generation high-frequency switching power diodes (0.7V). With a high-current parallel structure and patented transformer design, efficiency can reach 94% or more.
This type of power supply has been applied in many large projects both domestically and internationally over the years. Its energy-saving performance is obvious, and it operates reliably and stably. The equipment has been well received by numerous users.

After months of collaboration with our Indian partners, the system is now live at a government research facility, quietly powering the electrolyzers that split water into hydrogen. The difference? ​Stable DC power, minimized energy loss, and a big step toward sustainable hydrogen.​​

What’s next? The research team is excited about scaling up, possibly integrating solar power for a truly green hydrogen solution. We’re not just selling equipment—we’re enabling a cleaner energy future, one rectifier at a time.
