An analysis/simulation program for power electronic circuits

Digital simulation programs for power electronic convertors can significantly facilitate the process of product design and development. Existing programs typically employ detailed active component models which require long run times and a large amount of memory space. This situation worsens when personal computers are used as host computers. The proposed simulation program minimizes these disadvantages by avoiding these switch models and replacing the switches with open and closed terminals. It is limited by an inability to incorporate small signal switch models; as a result, it cannot differentiate among the various types of switches. Therefore, this program is suited for case studies where the exact type of switch used is not essential in predicting the steady state or transient behavior of the circuit being considered.
