The industry's highest power density power storage ground power regulator SiC module

     Daiheng selected Infineon's CoolSiC 2000V module as its innovative unit-type grid battery power regulator. In the process of reducing carbon emissions, grid energy storage batteries and their associated power regulators play a crucial role in the widespread adoption of renewable energy sources such as solar and wind. In order to improve the efficiency of power generation, storage and transmission, there is a growing demand for high-voltage batteries and power regulators. In addition, with the massive expansion of energy storage systems, finding suitable locations and minimizing construction costs have become major challenges.

     The grid-connected battery set power regulator launched by Daheng in 2024 is the first product in the industry to access batteries with 1500V DC high link voltage. The higher voltage allows the product to be used with high-capacity battery facilities, reducing the footprint of grid batteries by 40% compared to conventional products.

     The high power density is achieved by using Infineon's 62 mm CoolSiC MOSFET 2000V module (FF3MR20KM1H). In addition to SiC's characteristics of high voltage, better heat dissipation and high power density, Infineon's SiC products feature M1H trench technology that increases the gate drive voltage range and provides high robustness and reliability to cope with gate voltage spikes. The company pioneered the 2000V class for SiC modules. This innovation helps simplify the inverter circuit configuration. In addition, the optimized 62 mm package greatly reduces the system size, helping to improve efficiency and performance.

     Mr. Akihiro Ohori, General Manager, Development Division, Daheng Energy Management Systems, said, "In order to increase the voltage of the power regulator, the circuit configuration of a traditional 1200v device becomes complicated. However, by using Infineon's 2000 V SiC module, we were able to achieve a simplified circuit configuration and control design, thereby reducing development resources and footprint."

     Masanori Fujimori, Marketing Director, Industry and Infrastructure Division, Infineon Japan, said: "We are very pleased that our pioneering CoolSiC 2000V module has contributed to the development of the industry's highest power density grid battery power regulator. We are confident that Infineon's SiC technology will meet the need for greater efficiency in energy storage systems and will contribute significantly to the growth of renewable energy."
