Wide-Frequency Equivalent Circuit Modelling of a DC/DC Converter for Conducted Emissions

Modelling converters in DC grids for supraharmonic emissions is crucial for understanding their impact on power quality. These emissions, occurring at frequencies above traditional harmonics, can disrupt grid stability and require accurate representation. Models must capture the behaviour of converters for different operating conditions, accounting their non-linearities and interactions with the grid. This involves characterising primary and secondary emissions, as well as their propagation through the network. Advanced simulation techniques are employed to assess the combined effects of multiple converters and evaluate mitigation strategies. By accurately modelling converter emissions, researchers can develop effective measures to ensure the reliability and efficiency of DC grids.
