Infineon Technologies has been selected by a major electric motor company to provide its CoolSIC ™ The 2000 V module is an advanced unit type power regulator designed for storing batteries in the power grid. Grid storage batteries and their related power regulators are crucial in promoting the widespread application of renewable energy sources such as solar and wind power, which is also part of efforts to reduce carbon emissions.

The demand for high-voltage storage batteries and power regulators is increasing to improve the efficiency of power generation, storage, and transmission. In addition, the implementation of large-scale energy storage battery systems has added challenges in site selection and reducing construction costs.

The power regulator for grid storage batteries launched by Daimyo Electric in March 2024 is the industry's first product to successfully connect with an important DC link voltage storage battery of 1500 V. By increasing the voltage, the product is now compatible with high-capacity storage battery systems, significantly reducing the volume of grid storage batteries by 40% compared to traditional products.

High power density is achieved by utilizing Infineon's 62mm CoolSiC mosfet 2000 V module (FF3MR20KM1H). Infineon's SiC products have multiple characteristics that promote high voltage, improve heat dissipation, and achieve high power density. In addition, these products adopt M1H channel technology, which expands the range of gate driving voltage and improves the ability to withstand gate voltage spikes. Infineon is the first company in the industry to launch 2000 V grade silicon carbide (SiC) modules. This innovation has played a key role in simplifying the configuration of inverter circuits. In addition, the redesigned 62mm package significantly reduces the overall size of the system, thereby improving efficiency and performance.

The large motor company stated that the circuit layout of ordinary 1200 V equIPMent makes it difficult to increase the voltage of the power regulator. However, by implementing Infineon's 2000 V SiC module, they successfully achieved simplified circuit configuration and control design, thereby reducing development resources and required physical space.

Infineon Technology Japan is satisfied with the significant contribution made by its innovative CoolSiC 2000 V module in the development of power regulators for grid storage batteries, considering it to be the industry's best power density. They believe that Infineon's SiC technology will effectively meet the demand for improved efficiency in energy storage systems and significantly contribute to the expansion of renewable energy.
