Marelli Electric Powertrain
Fabio Alpiovezza was born in Milan, Italy, in 1969. He received the master’s degree in electrical engineering in 1994 from Politecnico Milan, Italy.After several years spent in power electronics design roles for different applications (railways, industrial and automotive) in 2016 he joined Magneti Marelli R&D department of the Hybrid and Electric Vehicles business unit in Venaria Reale, near Turin.
He is managing the Hardware Engineering Team with a special focus on high voltage inverters for hybrid and electrical vehicles (passenger cars and 2 wheelers). His area of responsibility covers electronics (control, driver and power electronics), PCB design, EMC design and mechanical design including CFD/CAE simulations. His current research interests include power electronics, cooling systems and driving stage designs for system optimization and integration.

Cooling channel optimization in power inverter design
The paper proposes a method to develop and optimize a proper cooling channel for a power module used in high-power three-phase inverters for electrified vehicles. Specifically, the cooling plate and the channel are designed by using steady-state 3D-computational-fluid-dynamic (CFD) tool. Subsequently, an optimization tool with dedicated algorithms is used to define the optimal layout, pin-fins and channel’s geometry in terms of inlet vs outlet pressure drop and power chip’s thermal performances. The simulations were performed using OptiSlang tool provided by Ansys.
