Characterization and analysis of electromagnetic interference in a high frequency AC distributed power system

High frequency quasi-square AC distributed power systems simplify the complexity of DC distributed power systems at the expense of greater generated EMI due to high values of dV/dt and dI/dt displayed in the bus waveform characteristics. To quantify EMI effects, the bus structure of a 300 kHz quasi-square waveform AC distributed power system is analyzed using the partial element equivalent circuits (PEEC) method incorporated in the software package InCa. Simulation and experimental results are compared and design guidelines to minimize EMI effects in AC distributed power systems are given.
