IEEE Power Electronics Magazine - March 2023 - 51

electronics-based power
systems
were considered as two of the most
critical applications
in the next
decade regarding the degree of
challenge to designers and reliability
engineers [9], reliability requirements,
and market
size. Finally,
the presentation called for efforts
in education through Master/Ph.D.
courses,
open-access
databases,
and the technical community in
this multi-disciplinary area.
The discussions and the presentaNeed
for faster
accelerated testing of
components and
systems combined
with a better
understanding of
physics of failure.
tions highlighted some future issues
to be resolved or to get more attention in the next decade
■ Early failures are still present in some renewable systems-means
to avoid them are needed.
■ Need for faster accelerated testing of components and
systems combined with a better understanding of physics
of failure.
■ AI may be applied for faster accelerated testing and
enable analysis to the end of life.
■ Fusion prognostic approaches can be a powerful tool for
end of life detection.
■ Better physics of failure models for humidity/water and
moisture impact.
■ Validations of life-time calculation and predictions will
increase thrust to modern reliability engineering analysis
methods.
■ Need for more research test infrastructure for battery/
storage and power electronic components/converters
including mission profile emulators to test for real
applications.
■ Better condition monitoring methods applying physics
of failure models and eventually add physics informed
neural network in the models (PINN).
■ Initiatives should be formed for research available open
access test data.
■ Develop more educational programmes in this field.
■ A technical committee working with these aspects could
be formed in the IEEE Power Electronics Society.
