Abstract:
This paper describes different thermal calculation methods and their impact on the lifetime estimation of power electronic devices in Modular Multilevel Converter (MMC) for high voltage DC transmission (HVDC) application. An algorithm based on the Fast Fourier Transform (FFT) is presented, which enables a fast and precise lifetime estimation for up to several hundred devices at the same time. The advantages and limitations of this method are discussed.
