A new circuit analysis and design simulator "TOKUZO"

High-performance as well as user-friendly circuit simulators are powerful aids for power electronics engineers. This paper presents a new circuit analysis and design simulator named TAP-T (transient analysis program "TOKUZO") mainly for power electronics use. It offers ATP/EMTP like or more convenient CAD environment. It is almost free from the numerical oscillation problems which annoy ATP/EMTP users. This feature attributes largely to TAP-T's reasonable counter-measures against switching logic conflicts. Two benchmark tests are carried out on circuits designated by IEE JAPAN to verify high accuracy and short computation time of TAP-T.
