The world-renowned semiconductor manufacturer Rom (headquartered in Kyoto, Japan) fourth-generation SiC MOSFET and gate drive IC have been used by Hitachi Anstelmo Co., Ltd., Japan‘s advanced auto parts manufacturer (hereinafter referred to as "Hitachi Anstelmo"), for inverters for its pure electric vehicles (hereinafter referred to as "EV").

In the global effort to achieve a carbon-free society, the electrification process of automobiles has accelerated. Against this background, the development of more efficient, smaller and lighter electric powertrain systems has become the only way. Especially in the field of EV, in order to extend the range and reduce the size of the on-board battery, it has become an important topic to improve the efficiency of the inverter that plays the driving core role, and the industry has high expectations for silicon carbide power components.

Since Roma took the lead in mass production of SiC MOSFET in 2010, Rome has always maintained an advanced position in the industry in the development of SiC power component technology. Among them, the newly launched fourth-generation SiC MOSFET improves the short-circuit tolerance time and achieves ultra-low on-resistance in the industry. When using this product in the car inverter, the power consumption can be reduced by 6% compared with the use of IGBT (according to the international standard "WLTC fuel consumption test"), which is very helpful to extend the range of electric vehicles.

Hitachi Anstemo has been committed to the development of advanced technologies related to automotive motors and inverters for many years, and has provided a large number of products for the increasingly popular EV, with a proud market performance in this field. This time, in order to further improve the performance of the inverter, Hitachi Anstemo used SiC power devices in the circuit of the main drive inverter for the first time, and plans to supply corresponding inverter products to global automobile manufacturers, including Japanese automobile manufacturers, from 2025.

In the future, Rom will, as a leading enterprise in SiC power components, continue to expand the product lineup, and combine the technical advantages of peripheral components such as control IC, which can stimulate the performance of components to a greater extent, and continue to provide power solutions that are conducive to automotive technological innovation.
