PSpice is a powerful general purpose analog circuit simulator that is used to verify analog or mixed digital circuit designs and to predict the circuit behavior. Its simulation waveforms is nearly as same as the experimental waveforms. The overall working stages of Boost converter is simulated and analyzed by PSpice. All the stages of stored energy elements of boost converter are also introduced. Some simulation waveforms are given to verify the analysis. Thus the understanding of boost converter is deepened.
