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. Impl...
