Constantinos has been working in the automotive industry since 2009. Most recently as a Systems Team Leader at Delphi Technologies, he headed the design of a diesel exhaust aftertreatment controller and software, destined for use in the Asia Pacific region. In 2006, he was awarded a BEng in Electronic Engineering by the University of Sheffield and in 2016, an MSc in Electrical and Electronics Engineering with distinction by the University of Greenwich. Outside work he mainly enjoys movies, and games but also dabbles in music with his guitar, he also enjoys a good coffee with friends. He joins the AAPS CDT with an interest in Propulsion Electrification and hopes to further his own and his industry's knowledge in the area of Power Electronics and Wide Bandgap semiconductor devices as we progress to cleaner transport systems.
A smart and high power density charger is the key power electronics converter to overcome challenges such as range anxiety, slow charging for battery electric vehicles and plug-in hybrid electric vehicles. Wide bandgap (WBG) semiconductor devices, such as SiC and GaN, with fast switching transitions provide a solution to meet stringent automotive requirements for high power on-board chargers, while maintaining a compact size and lightweight design. Constantinos' PhD will be investigating an innovative multi-level topology tailored for WBG devices. Multi-level topologies offer many advantages such as modularity, scalability, lower losses, limited voltage gradients, and higher AC voltage quality. The modularity of a multi-level topology also lends itself to higher fault tolerance, which is attractive in safety-critical applications. It is widely-accepted as the most promising topology for high voltage and high power applications. In automotive applications, this topology will enable the use of higher voltage DC bus systems and also help facilitate the penetration of low voltage WBG devices in these applications.
