Abstract
The aim of this paper is to provide a simplified methodology for conducted electromagnetic interference (EMI) predictions of DC-DC converters using two classical simulation approaches: time domain and frequency domain simulations. The boost converter is investigated and modeled using information provided by manufacturers without any measurements beforehand. By proposed simulation techniques, it is possible to fast approximate conducted EMI with reasonable accuracy at design stage. Finally, the validity of proposed models is proved by comparing the simulated results with measured results in terms of common mode, differential mode and total noises at frequency range from 150 kHz to 30 MHz.
