ROHM Semiconductor and Vitesco Technologies Form Long-Term SiC Supply Partnership
Partnership enables capacity assurance for energy-efficient silicon carbide power semiconductors
Santa Clara, CA and Kyoto, Japan, June 19, 2023 (GLOBE NEWSWIRE) -- , an electronic parts manufacturer, and Vitesco Technologies, a leading international manufacturer of modern drive technologies and electrification solutions, today announced they have formed a long-term silicon carbide (SiC) supply partnership worth more than one billion U.S. dollars (2024 through 2030). The development partnership between the companies, which started in 2020, formed the basis for the supply partnership.
Vitesco Technologies’ advanced inverters with integrated ROHM SiC chips will be adopted by two customers, to be applied inside electric vehicle powertrains. Vitesco Technologies will start supplying a first series project as early as 2024, ahead of the originally targeted timeline.
SiC devices enable the design of particularly efficient power electronics, such as those needed for electric car inverters. SiC chips are a key technology, particularly for high voltages and for vehicles with demanding range targets and optimum overall efficiency. During the existing development partnership, with ROHM the relevant SiC chips were further optimized for use in automotive inverters starting in 2024.
“The supply partnership agreement with ROHM is an important building block for securing Vitesco Technologies' SiC capacities in the years ahead,” said Andreas Wolf, CEO of Vitesco Technologies, at the signing ceremony in Regensburg, Germany. “We have had very good experience in our development cooperation so far and are now looking forward not only to continuing it, but also to intensifying it further,” adds Wolf.
“In the high-growth automotive market, SiC is a pathfinder for higher efficiency. With an expected higher market share of more than 30 percent, we are strongly positioned here and have gained a strategic partner in Vitesco Technologies for further market penetration,” said Dr. Kazuhide Ino, Member of the Board, Managing Executive Officer, and CFO of ROHM Co. Ltd., at the signing ceremony.
Small cause – big effect
Silicon carbide belongs to the so-called wide bandgap semiconductors, whose wide bandgap (simplified: the energy gap between the non-conductive state and the conductive state of the electrons in the material) enables lower electrical resistance, fast and low loss switching chips for power electronics. At the same time, SiC chips are more thermally resistant, so that the power density of electronics can be increased.
Thanks to these features, SiC electronics have reduced conversion losses compared to conventional silicon (Si). Especially at high voltage levels such as 800 V, SiC inverters are more efficient than Si models. Since 800 V is the prerequisite for fast and thus convenient high-voltage charging, SiC devices are at the beginning of a worldwide boom. Reduced conversion losses in the inverter are also significant for the overall efficiency of electric driving and thus for range. Competition for sufficient capacities in components made of this high-tech material is correspondingly fierce.
