Elite Power Simulator and Self-Service PLECS Model Generator

The purpose of this application note is to explain the technical advantages included in the online Elite Power Simulator and Self−Service PLECS Model Generator (SSPMG) offered through onsemi. This note provides more details on how the online tools have been implemented and the features available. The application note begins by covering some basics with regards to SPICE and PLECS models. Next details behind switching loss extraction techniques and the influence of parasitics are covered. The concept and benefits of a virtual switching loss environment are introduced. This virtual environment also includes the ability to study system performance dependencies on semiconductor process variation. Finally, a PLECS model valid for both hard and soft switching and the associated ramifications are detailed. The conclusion explains the reasons why the onsemi tools are more accurate compared to other industry tools for power electronic system level simulation.
