Dr. Rainer Kaesmaier

Since 2018 Dr. Rainer Kaesmaier is Managing Director for the Global Product Group Semiconductors of Hitachi Energy, leading the semiconductor business with its global manufacturing and R&D footprint for the power semiconductor product portfolio which compromises GTOs, IGBTs, IGCTs, Thyristors, Diodes for market segments such as energy transmission & distribution, transportation & rail, renewable, industry and e-mobility. He is a semiconductor industry veteran having held various management and executive positions in the sector for more than 25 years, covering areas of global responsibility in business strategy and development, business transformation, technology and engineering, operations and production, R&D, as well as sales and marketing. After stations at Siemens, Infineon, Qimonda, and the European semiconductor manufacturer LFoundry, he assumed the responsibility for the global semiconductor business of Hitachi Energy. In addition to that, Rainer is since 2019 also member of the management board for Hitachi Energy Switzerland Ltd.

从更广泛的电力电子角度看电动汽车的功率半导体趋势

The opportunities for WBG Power Semiconductors in automotive applications are recently widely discussed due to the immense growth potential of the new electric vehicle market. With the speed of market adoption, also the full supply chain needs to be developed.

This is not only the case within the semiconductor products supply from material – i.e. SiC epi substrates – to the chip and then to the module. It needs to be setup in the full industry value chain, from power generation via power transmission to the grid and charging infrastructure, then finally to the electric vehicle EV itself. This full industry value chain needs to be then differentiated depending on the final EV applications which have a wide variety of conditions to reflect: The volume driver is EV passenger cars, here already in a spread of technology requirements from high performance cars to standard models with less power needs. It becomes further differentiated, if we go up the EV types, e.g. in its intrinsic mass, from buses and trucks to electric locomotives.

The presentation will give an overview, how from a power electronics system provider view, the new power semiconductor technologies, i.e. SiC, drives the development of the new system concepts along the industry value chain applications due to the technological specific advantages of the new power semiconductor developments.
