Electrical Machines and Power Electronics for Starter-Generators in More Electric Aircrafts: A Technology Review

Abstract

Safety-critical power conversion systems play a major
role in the paradigm shift towards more electric aircraft
(MEA) architectures. This paper reviews the electrical machines
and their power electronic systems that are currently competing
in the application of integrated starter-generators (S/Gs) in
MEA power systems. Motivated by the strict requirements of
sufficient electrical starting capability, super-high power density
and ultra-high reliability, additional considerations on the overall
system design are necessary, including the power electronic
converters (PECs) and integrated thermal designs. These aspects
are discussed not only in the light of their many benefits but
also of the challenges introduced by the continuous advancements
and emerging innovations in the power conversion technology. In
achieving the MEA goals and capitalize on all potential benefits,
optimization-based design approaches will be necessary, where
the aggregation of electric machines, PECs and the aircraft grid
is considered as an integrated system to be optimized. This review
highlights the importance of these aspects and offers a view on
future perspectives and open issues.
