A short note on frequency-domain damage calculation for power semiconductors reliability control design
(Fachhochschule Nordwestschweiz FHNW, 10.02.2025) Rezaeizadeh, Amin; Mastellone, Silvia
In this short note, we give a simple derivation of the damage calculation for power semiconductors based on the frequency-domain approximation of damage. This analysis can be further used to design linear control systems aimed at reducing the damage to the semiconductor switches in power converters.

Fast and efficient estimation of resonant modes. A case study of mechanical drivelines
(Institut für Elektrische Energietechnik, Hochschule für Technik FHNW, 28.08.2024) Rezaeizadeh, Amin; Mastellone, Silvia
This work presents the development of an online parameter estimation algorithm for the identification of resonating modes in a linear system of arbitrary order. The method employs a short-time Fourier transform of the input and output signals and uses a recursive least square (RLS) algorithm to detect resonant frequencies and damping factors of the resonant modes.
