With the rise of the Green Hydrogen industry, the IGBT hydrogen power supply is more responsive and more suitable for the fluctuating wind and photovoltaic hydrogen production projects and large-volume, high-power electrolyzers, iGBT is expected to become the hot spot of enterprise layout and the trend of future technology development. In the technology path, the company is from the device upgrade, circuit optimization and module system optimization three levels of research and development. IGBT power supply focuses on high-power breakthrough, as well as to improve the efficiency of low-load rectifier, IGBT + PWM rectifier will be with the deep integration of green electricity and green hydrogen, and continue to promote the development of large-scale electrolytic cell, integration, low energy consumption.
