This paper presents a modified small-signal model of a voltage source inverter (VSI) that captures model nonlinearities such as dead time and modulation effects that were not presented in the literature. Previous research has concentrated on developing compensation methods for these types of phenomena in a switching model, but none actually derived an analytical model that can predict them. In this...
A generalized terminal model has been proposed to predict the conducted electromagnetic interference (EMI) from a boost converter. The results of conducted emissions have shown a good agreement up to 50 MHz. The same technique was also successfully applied to extract a terminal model of buck converter. This paper extends the generalized terminal modeling approach to a larger class of power converters...
This paper presents an enhanced average model of a voltage source inverter (VSI) that can accurately predict some of the low frequency phenomena only seen by the switching models. These phenomena include the dead time, voltage drop across switching devices (switch & diode), different modulation and minimum pulse width. Simulation and experimental results with a 2 kW prototype is used for validation...
