Using the SIMPLIS Pre-POP Transient Analysis

An optional Pre-POP Transient analysis is added to SIMetrix/SIMPLIS v9.30 as a subtask of the Periodic Operating Point (POP) analysis.  The Pre-POP Transient analysis, if enabled, is the first subtask to be run in the POP analysis.  The Pre-POP Transient analysis stops when either it has reached the specified stop time or when the logic output of a certain triggering gate has registered a 0-to-1 transition.  After the Pre-POP Transient analysis is complete, the simulation of “N cycles before launching POP” is run next, followed by the core POP process. The Pre-POP Transient analysis is useful for complex systems requiring extensive initialization of a large number of energy-storage elements and sequential logic circuits, allowing the core POP process to be launched only after the system has settled to a reasonable starting point.

In addition, if the Pre-POP Transient analysis is enabled, the POP analysis now supports automatic resetting of the “Maximum period” parameter according to the switching periods observed by the POP trigger during the Pre-POP Transient analysis.

In this webinar, we will walk through an example that details the Pre-POP Transient analysis and its options.  We will also discuss when it is appropriate to use this analysis.
