Three-day Advanced SIMPLIS Training

Date

October 25th-27th in Santa Clara, CA

This three-day course is designed to provide current users with the advanced understanding needed to become highly skilled at creating SIMPLIS models of switching power supplies.

Location:

Embassy Suites - Silicon Valley
2885 Lakeside Drive
Santa Clara, CA 95054

Course Description:

The first two days of the class will cover the following topics:

  • How to create SIMPLIS models that run fast and quickly find the Periodic Operating Point
  • How to parameterize a SIMPLIS model and how to create a custom Edit Dialog
  • Methods to create time-domain models for critical power stage components (MOSFETs, drivers, rectifiers, inductors and transformers)
  • Fundamentals for modeling control circuits
  • Essential details for conducting a comprehensive analysis of power supply performance
  • Techniques for measuring time domain waveforms and AC analyses such as Bode plots, input and output impedance

The SIMPLIS Design Verification Module (DVM) is covered in depth on the third day. The DVM module automates testing, the collection of scalar and graph data, and generates an HTML report with links to the simulated data. In addition, predicting the interaction between MOSFET driver limitations and losses in power MOSFETs will be covered on the third day.

This course makes extensive use of hands-on exercises that are

Instructors:

Tom Wilson has 26 years of experience designing, manufacturing and marketing switching power supplies. During most of that time, he has been active in applying circuit simulation to the power supply design process. He has been a user of SIMPLIS since its earliest incarnation. He is currently having lots of fun working with SIMPLIS users to address their design and analysis challenges. Tom received his Masters and Doctor of Engineering degrees from UC Berkeley.

Matt Fortin has 4 years experience as an applications engineer supporting a wide array of integrated circuits, including switching and linear regulators, amplifiers, interface devices, and optoelectronics. During this time, he became an advanced SIMPLIS user while helping develop power electronic integrated circuit models. Matt joined SIMPLIS Technologies at the beginning of 2016 and has a B.S.E.E. from the University of Central Florida.
