SIMPLIS MDM Beta Tutorial

The SIMPLIS Magnetics Design Module (MDM) is available starting with SIMetrix/SIMPLIS version 8.40. If you would like to evaluate MDM, please send an evaluation request to:

The objective of this tutorial is to introduce you to the basics of the SIMPLIS Magnetics Design Module (MDM). This will be done through two examples:

  • The design of an energy-storage inductor for a 12V-to-1.2V, 10A output, Buck DC-to-DC converter switching at 500kHz
  • The design of a transformer for an isolated AC line-to-5V, 2A output self-oscillating flyback converter

In this tutorial you will learn how to do the following:

  • Use SIMPLIS MDM to create a physical model of an inductor and a transformer from standard magnetic parts, including cores and wires, using SIMPLIS MDM.
  • Obtain detailed estimates of losses inside magnetic components via postprocessing of simulation results in SIMPLIS MDM.
  • Analyze the postprocessing results to improve your design.
  • Define the thermal aspects of the design and operation of a magnetic device inside a power supply.
  • Save and load magnetic device designs (geometries).
  • See how SIMPLIS MDM's "Virtual Winding Machine View" can provide high-level documentation on how to wind the transformer you designed.

More comprehensive documentation for SIMPLIS MDM will be released in the near future.
