Digital Power Supply Design Workshop

The workshop is three days long and is aimed at analog PSU designers and embedded systems engineers who need to design high performance stable digital power supplies. A 4th optional day is available in selected venues which covers design and implementation of digital PFCs.

First the engineering concepts, theoretical material, step-by-step design procedures and power supply design equations are thought in the class and then these are all put onto practice with numerous laboratory exercises on real digital power supplies. The design practices taught in the class and carried out in the labs can be applied to any MCU*

Agenda
Typically the morning session is dedicated to the study of theory and principles, whilst the afternoon session focuses on laboratory exercises to consolidate the theory.
An overview of the course syllabus is given below:

Day 1: Introduction to Digital Power Programming

  • Introduction to digital power
  • Closed loop control of switch mode power supplies in analog and digital domains
  • Biricha templates and easy project setup I/O pins, PWM, ADC, Interrupts etc., ideal for non-programmers
  • Number formatting for digital Compensator design with:
    • floating point and 32 bit IQMath e.g. TI fixed point Piccolo C2000 devices
  • Dealing with TI CLA core
  • Hands-on Laboratory exercises*


Day 2: Digital Power Supply Design

  • Detailed study of analog power supply design fundamentals
  • Detailed discussion and design of digital power supplies
  • Implementing a simple digital controller for your digital power supply
  • Digital voltage mode controller design
  • Off-line power supply design considerations: Limit cycling, Hi-Res PWM, ADC quantization
  • Hands-on Laboratory exercises*


Day 3: Peak Current Mode Control and Running Multiple Control Loops

  • Running multiple power supplies using the main core and the CLA
  • Detailed review analog peak current mode design
  • Removing sub-harmonic oscillation and slope compensation
  • Digital peak current mode controller design
  • Analog and digital slope compensation
  • Phase margin erosion in digital domain due to delays
  • Hands-on Laboratory exercises*


Day 4: Digital PFC Design & Implementation (Optional Extra Day +$500)
Learn how to design and stabilise single phase and interleaved digital power factor correction systems from ground up quickly and easily during this in-depth laboratory based optional day.

  • Fundamentals of power delivery, power quality & PFC
  • Single Phase CCM Boost PFC topology operation & design
  • Digital PFC translated from analog PFC
  • Step-by-step digital PFC control loop design (voltage loop and current loop)
  • Voltage feed-forward & filter design in digital domain
  • Digital interleaved PFC
  • Hands-on Laboratory exercises*


During this day we will start from basic principles and cover the entire design, loop stabilization, meeting the regulations and component selection. To verify all of the theory, in real life you will then implement your digital PFC design in our well-equipped lab.

The participants will typically work in pairs at a workstation. Each workstation will be equipped with a PC with relevant development software, oscilloscope and several digital power supplies.
When registering you will be able to choose either a 3 or 4 day option (+$500).

* All labs for the the workshop are based on TI's C2000 range of of MCUs on digital power teaching kits specially designed for this workshop. Commercial WDS license will be valid for 6 months and is subject to unrestricted access to the internet.

Cost: 
$1,995 USD
Duration: 
3 days
