Abstract
Often device capacitance is neglected as a loss path in power converters. In high voltage-low current conditions it can lead to significant power loss as the capacitance is charged and discharged many times a second. Switch models are usually either ideal or include so much detail they slow a converter simulation. This paper presents a behavioral model that fills in between the two extremes. Implemented in Matlab/Simulink the device accounts for resistance and capacitance as well as the antiparallel diode. Switch power loss accounting is also covered. The switch model is then included in a resonant power converter model and compared to a prototype converter. A feedback controller for the converter model is also demonstrated.
