Trends in Power Electronics with focus on wide-bandgap materials technology and applications
President, Technology, Manufacturing, Quality and Supply Chain
ABSTRACT – The evolution of power electronics has been driven by the demand for more efficient, reliable and cost-effective power conversion and control. The need for power electronics has never been greater as we face the urgent global challenge of decarbonization. Power technologies enabled the development of high-efficiency power supplies, inverters for renewable energy systems. Electric vehicles rely on power electronics to control the motor drive, battery charging and other critical functions. Power electronics also enable he development of fast charging infrastructure, which is essential for making electric vehicles more practical and convenient. There are several types of power semiconductors used in electric vehicles and power conversion applications, including insulated-gate bipolar transistors (IGBTs), metal-oxide-semiconductor field-effect transistors (MOSFETs), based on traditional silicon technology. Today, power semiconductors technologies continue to evolve with the development of new materials, devices, and control techniques. Some of the latest developments in power electronics include wide-bandgap (WBG) semiconductors, such as silicon carbide (SiC) and gallium nitride (GaN), which have higher switching speeds and can operate at higher temperatures than traditional silicon devices. These new materials are enabling the development of more efficient and compact power converters for a variety of applications, from electric vehicles to power grids.

Energy transition: electrification, digitalization, market, resilience
Politecnico di Torino
ABSTRACT – The energy transition is a global trend firmly under way, going on now for several years for tackling environmental and climate-related concerns. In the last years, the acceleration of the climate related policies and initiatives has put electricity system at the centre of the debate concerning the decarbonisation of society. While it is impossible to envisage the diminution of greenhouse gases emissions without an electricity-centred economy, there are many issues to be solved regarding technologies, investments, market regulation, and social equity at the national and global scales.
The speech will highlight the role and limitations of public policies in the promotion of electrification, and the synergies with the digitalization of the assets and systems. On the other hand, it will discuss the emerging problems about markets caused by the prevalence of renewable energy sources, and the need to rethink the resilience of systems for anticipating the set of capabilities that will be required for the reliable and secure supply of energy.

Enabling the Energy Transition
ABSTRACT – Climate change is currently imposing decarbonization challenging goals with the purpose of reducing CO2 emissions both at global and local level.
To support the energy transition Italy is deploying the PNIEC and PNRR economic programs, to sustain the growth of green energy production and to enable consumptions electrification.
In this framework, the DSO role is crucial to connect to the distribution infrastructure both final customers and small energy producers. For this reason, our electrical grid will be widespread, efficient and resilient and will develop faster than ever before, where our primary substation will act as its pumping heart.
To match a fast-paced grid expansion E-Distribuzione will implement quick works’ scheduling, Project management and control tools, extensive components’ standardization and innovative contract management methodologies. The two main examples are the Licensing Engineering contract, for the land scouting and the permitting process management, and the EPC contract, for end-to-end works’ management, from the engineering to the commissioning.
These are our goals, but they are also the issues for everyone who wants to look forward.

Honorary Award 2022 of the IEEE Italy Section for “The rebuilder of European Semiconductor industry, able to combine profit and environmental/social sustainability”
SPEAKER BIOGRAPHY – Pasquale Pistorio graduated in 1963 in Electrical Engineering from the Polytechnic of Turin. He joined Motorola in Milan, Italy, in 1967, and rose through the ranks to become, by 1977, Corporate Vice President of the company, based in Phoenix, Arizona, and General Manager of the International Semiconductor Division. In July 1980, Pistorio accepted the challenge to return to Italy as President and Chief Executive Officer of the SGS Group, the only Italian microelectronics company. Pistorio turned around the state-owned company within two years, and his commitment to build it into a large scale broadline semiconductor manufacturer led to one of his most significant achievements: the successful integration of SGS with the semiconductor division of Thomson-CSF, in 1987. As President and CEO of the new company SGS-Thomson (subsequently renamed STMicroelectronics), Pistorio developed its diverse product portfolio based on high-growth applications and a worldwide network of strategic alliances. The successful business model enabled STMicroelectronics to position itself amongst the top five seminconductor manufacturers by the year 2000, and the company was listed in the New York, Paris, and Milan stock exchanges. While bringing the near bankrupt SGS from about 100 Million USD in sales in 1980 to a leading world company STMicroelectronics with 8.7 Billion USD in revenues in his last year as CEO in 2004, Pistorio also forged a strong company culture characterized by integrity, pursuit of excellence, and commitment to social and environmental responsibility.
As early as 1993, Pasquale set up a companywide Environmental Decalogue with quantitative targets and programs for emissions reductions, waste reduction, recycling, among others, and a roadmap towards Carbon Neutrality, making the company within a few years a pioneer and leader in sustainability, winning numerous accolades including the US Environmental Protection Award for two years, and the European Quality Award. In 2002, Pistorio was voted among the top 50 “Stars of Europe” by Business Week and number 1 in Time Magazine’s “Top 25 Movers and Shakers” list. As a member of the UN ICT Task Force under Kofi Annan, Pistorio founded the STFoundation in 2001, to provide IT Literacy skills to highly marginalized communities. Today, STFoundation counts nearly one million trainees globally.
During his career, Pistorio championed pioneering European programs such as JESSI (Join European Sub-micron Silicon Initiative) and MEDEA (Microelectronics for European Applications). He has been Chairman of the Advisory Council of the European Union’s Nanotechnology Platform (ENIAC), sat in the Executive Committee of the World Business Council for Sustainable Development and at the European Round Table (ERT) of Industrialists.
Upon his retirement as President and CEO of STMicroelectronics in March 2005, he was nominated Honorary President of the company by the Advisory Board. The same year, he created the Pistorio Foundation, dedicated to providing educational opportunities to children in need.
Pistorio has served as Chairman of Telecom Italia in 2007 and as Vice President for Innovation and Research of Confindustria (2005 to 2009). He has been a board member of Fiat, Telecom Italia, Brembo, ATOS Origin, Chartered Semiconductor, and STATS ChipPAC. Pistorio is Cavaliere del Lavoro in Italy, Officer of the National Order of Merit of Malta, Officier de la Legion d’Honneur and Commandeur de l’Ordre National du Merite of the French Republic, recipient of the “Ouissam Alaouite” by the kingdom of Morocco, and Honorary Citizen of Singapore. He has been awarded the Lifetime Achievement Award by Reed Electronics Group, as part of the European Electronics Industry Awards; the IEEE Ernst Weber Engineering Leadership Recognition; the ACE Lifetime Achievement Award by the EETimes; the IEEE Robert N. Noyce Medal Award; and the Ellis Island Medal of Honor.
Pistorio has received Honorary Degrees from the Universities of Genova, Malta, Pavia, Catania, Palermo, del Sannio Benevento, Bicocca and Bristol.
