Abstract

All parasitics such as switch conduction voltages, conduction resistances, switching times and ESR''s of capacitors are counted in the new state-space modeling based on non-ideal switching functions. An equivalent simplified model is derived from the complex circuit with parasitics. Hence the results are very simple and exact, which are very important features of modelings. The pole frequency, dc voltage gain, and efficiency of the general converter, the buck-boost converter are analyzed and verified by the experiments with good agreements with the theories. This may be a good summary for the previous works concerned with parasitics.
