Abstract

Modern power electronic systems operate with a trend of increasing speeds, voltage, power and temperature. In order to reduce the simulation time for electromagnetic(EM) modelling in power electronic systems, Model Order Reduction(MOR) technique is applied. The conventional MOR method uses a single expansion point at DC or 0Hz but this doesn’t give accurate results over a wide range of frequencies. In this work, a Krylov subspace based MOR technique method using multiple expansion points is introduced to accelerate the simulation. A test case will be given to demonstrate the application of multi-expansion point MOR method in EM modelling to evaluate multi-expansion point MOR compared with single point MOR in wide frequency range. Eigenvalue analysis will be illustrated to analysis the reason of the limitation of standard single-point MOR method.
