Emerging Power Management Solutions Course

morreale Tuesday 31 of May, 2022

The Emerging Power Management Systems short course was held from May 3 to May26, 2022 virtually through the University of Limerick. The short course consists of eight 2 hour lectures followed by a question and answer session. The course is taught by Aleksandar Prodic from the University of Toronto.

The course was fascinating. The professor described the Small Ripple Approximation (SRA), the Inductor Volt-Second Balance, and Capacitor-Charge Balance methods of analyzing Switch Mode Power Supplies (SMPSs). The professor used the approximation on boost and buck converters to create an equivalent circuits that replaced the switching elements with a transformer with a winding ratio related to the duty cycle of the controller plus some voltage and current sources. Then the model can be simulated in SPICE using AC analysis without complex switching signals to worry about.

Course Program

The course program outline is shown below:

Text book

One of the text books recommended for the course was the Fundamentals of Power Electronics by R. W. Erickson and D. Maksimovic.

Fundamentals of Power Electronics

Simulators

We used the Typhoon-HIL Control Center power simulator with the Sandia National Laboratories Xyce SPICE simulator for our homework assignments. The Xyce simulator was selected because it is well suited for simulating switching power converters.

Typhoon-HIL

A license for the Typhoon-HIL power simulator was provided for the course and may be available for free generally. Follow the download link below and request a license. Typhoon-HIL also provides an interface for Xyce SPICE simulator which can be downloaded from GitHub.

Xyce

The Sandia National Laboratories SPICE simulator Xyce is free and can be downloaded from the Xyce download website after registering.
