Infineon Technologies AG announced that its CoolSiC™ 2000 V modules have been selected by Daihen Corporation for their innovative unit-type power conditioners for grid storage batteries. In the journey towards reducing carbon emissions, both grid storage batteries and the power conditioners that are linked to them play a vital role in facilitating the wider adoption of renewable energy sources like solar and wind power generation.
There has been an increasing demand for higher voltage storage batteries and power conditioners to enhance the effectiveness of power generation, storage, and transmission. Moreover, with the expansion of storage battery systems on a larger scale, finding suitable locations and minimizing construction costs have emerged as significant challenges.
The unit-type power conditioner for grid storage batteries launched by Daihen in March 2024 is the first product in the industry to achieve connection to storage batteries at a high DC link voltage of 1500 V. The higher voltage enables the product to be used with large-capacity storage battery facilities, which has resulted in a 40% reduction in the footprint of grid storage batteries compared to the conventional product.
The high power density is achieved by using Infineon’s 62 mm CoolSiC MOSFET 2000 V module (FF3MR20KM1H). In addition to the characteristics of SiC that enable high voltage, better thermal 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 against gate voltage spikes. Infineon was the pioneer in the industry to introduce the 2000 V class for a SiC module. This innovation has been instrumental in simplifying the inverter circuit configuration. Furthermore, the optimized 62 mm package has led to a substantial reduction in system size, contributing to enhanced efficiency and performance.
Mr. Akihiro Ohori, General Manager, Development Department, Energy Management System Division, Daihen, said, “In order to increase the voltage of power conditioners, the circuit configuration of conventional 1200 V devices had become complicated. However, by adopting Infineon’s 2000 V SiC modules, we were able to achieve a simplified circuit configuration and control design, thereby reducing development resources and the footprint.”
Masanori Fujimori, Marketing Director of the Industrial & Infrastructure Segment at Infineon Technologies Japan, said, “We are very pleased that our pioneering CoolSiC 2000 V module has contributed to the development of the industry’s highest power density power conditioners for grid storage batteries. We believe that Infineon’s SiC technology will address the need for higher efficiency in energy storage systems and will greatly contribute to the growth of renewable energy.”

Power Master Semiconductor has released 2nd generation of the 1200V eSiC MOSFET to meet the requirements of higher efficiency, high power density, robust reliability, and ruggedness in various applications such as DC EV charging stations, solar inverters, energy storage systems (ESS), motor drives and industrial power supplies. 1200V eSiC MOSFETs offer significant system advantages such as higher power density, efficiency and less cooling effort due to its much lower power losses.
Therefore, SiC MOSFETs are gaining popularity especially for renewable energy systems, EV charging systems that required higher power density, efficiency and robustness. DC EV charging station is level-3 charger and its power level is increasing by modular configuration as demand of faster charging time and higher battery capacity of EV. DC EV charging provides a mostly constant current output for wide DC output voltage range (200V to 900V) and load profile.
The new generation of 1200V eSiC MOSFET, Gen2 improved key FOM characteristics such as gate charge (QG), stored energy in output capacitance (EOSS), reverse recovery charger (QRR) and output charge (QOSS) by up to 30% compared to previous generation. This new generation SiC MOSFET technology offers significant system advantages such as smaller, lighter, higher efficiency, and less cooling effort thanks to its much lower power losses in various power conversion applications.
1200V eSiC MOSFET Gen2 offer excellent switching performance and 100% tested avalanche capability. It achieved 44% lower switching loss compared to the previous generation by extremely low miller capacitance (QGD).
Power Master Semiconductor is steadfastly committed to developing cutting-edge power device solutions that prioritize efficiency and sustainability,” said Namjin Kim, Sr. Director Sales & Marketing. “The introduction of our new generation of 1200V eSiC MOSFET marks a substantial leap forward in facilitating the development of cleaner, more efficient power systems. We are confident that the 1200V eSiC Gen2 MOSFET will play a transformative role in high-performance applications.
