Pietro Scalia
Sr. Director, Power Systems & Solution Marketing, Industrial & Multi-Market
Renesas
Pietro is currently the Head of Marketing of Power at Renesas Electronics, which he has recently joined to contribute to power business growth across the different market segments. He covers Si to WBG components in industrial and automotive segments, while addressing major trends such as AI and electrification. His team of BU Power BDMs is spread into three regions, defining and supporting combo power solutions for all the applications.
His previous activity at Analog Devices (2023-2024) has been dedicated to lead the efforts in expanding and scaling ADI power offerings, with his worldwide team working closely with Field and all Power Business units to create customer-centric Power Solutions based on entire power portfolio and across all market segments and applications. Prior to that, he was with onsemi (2021-2023) as part of the Automotive EV-Traction Solutions business unit, where he led the Application and PLM team of Munich. Before that, he was with Texas Instruments for 11 years, after moving from Italy to Germany in 2008. At TI, his worldwide Business Development responsibilities were centered on Power products in applications from Telecommunications and Cloud, leveraging his earlier career in Siemens, Ericsson and ST Microelectronics and Academia, to Automotive systems.

Power System Architecture approach in Automotive X-in-1 Reference Design
The "X-in-1" approach in Electric Vehicles (EVs) refers to the integration of multiple essential components of the vehicle into a single, unified system or module. Renesas has created a reference design together with an automotive Tier1 to showcase the system value and also provide a flexible development ecosystem which can be leveraged to easily modify and develop variants of the end equipment. 8 functions have been integrated in a single box (8-in-1), significantly reducing the total volume by about 30% and unit cost by sharing or reducing 1) ECU case, 2) water jacket, and 3) high-voltage wires. The system integrates an OBC, a DC/DC converter, and an EV Traction Inverter. The combination of a single MCU and a PMIC controls all functions, which reduces BOM cost by dollars, and contributes to compact ECU integration. Practical performance has been achieved in the reference design. >99% inverter, >95% OBC & DC/DC power efficiencies. For the OBC and DC/DC, the multi-phase Totem Pole PFC showcases SuperGaN switches to be able to increase switching frequency, reducing the size of the system, while reducing heating elements, thanks to the superior efficiency achieved. A similar approach with our SuperGaN can reduce the switching losses in the secondary DAB stage. Finally, magnetic integration with single core allows to reduce the HV Battery voltage to the auxiliary one. Renesas’ power portfolio provided all the isolated drivers for the isolated topologies, the bias function and system power needed to supply the MCU, which is intended for several control functions. All software is developed using MBD (MILS and HILS simulations, Autocoder), significantly reducing coding workload and bugs, and it can be scaled for further development using the same architecture.
