Abstract

With the increasing complexity of electronic systems and their miniaturization, Electromagnetic Compatibility (EMC) concerns have increased due to the higher switching frequencies of buck/boost power converters. Electromagnetic Interference filters are used to comply with EMC limits. However, the optimal to-the-limit design of such a power system is difficult due to the large number of involved parameters which, in case of complex EMC simulation models, lead to prohibitively long simulation times. This paper develops a method based on wide-band surrogate models of a half bridge buck converter and its EMI filter, which is fast enough to allow 10,000 system evaluations in 4 minutes with an octa-core laptop. With the surrogate models, we demonstrate the feasibility of Multi-Objective Optimization (MOO) for minimizing common-mode emission and the size of the filter's common-mode choke. A computational advantage over LTspice simulations of at least 400 times has been achieved. © 2023 IEEE.
