May 18 Webinar – Basics of Digital Control of Power Electronics

Friday, May 14th, 2021

Our webinar series is back! Grab your lunch or a coffee and join us for this free webinar on the basics of digital control of power electronics.

From the comfort of your own desk you can join ELMG Digital Power for a free webinar to expand your knowledge and expertise about the advantages that digital electronics provides including:

* Flexibility
* Configurability
* Re-tuning the loop for component variation such as Electrolytic capacitor freeze out at low temperatures
* Management of the non-linearity of the converter
* Self-measurement of the loop response in closed and open-loop

and learn about the three key basics of digital control of power electronics these being

1. Limited number of bits.

2. Power converter characteristics including non-linearity

3. Limited PWM timer precision

This webinar will be hosted and presented by Dr. Hamish Laird, ELMG Digital Power’s CTO and a Principal FPGA and Power Electronics Engineer. Hamish has considerable experience in the design and implementation of varied digital control systems and IP for power electronics on FPGA platforms.

The webinar on Basics of Digital Control of Power Electronics: Where to start and what is important will be held May 18, 2021, at 12 Noon PDT on Zoom.

Spaces are limited.

Free Webinar – Digital Control of Power Electronics using Zynq

Friday, January 31st, 2020

If you have just sat down at your desk with a coffee, then put that aside for a minute and grab your diary. Review your schedule for Tuesday 4th February and consider this stellar opportunity: on that day ELMG Digital Power will be hosting a FREE webinar on Digital Control of Power Electronics using Zynq.

That’s right, from the comfort of your own desk you can join ELMG Digital Power (Members of the Xilinx Alliance Program) for their Zynq Digital Power Webinar and expand your knowledge and expertise by discovering:

* What is important in digital power, including numeric precision and latency
* Why you would use a FPGA for digital power and why the Zynq SoC in particular
* Key issues in digital controllers in programmable logic, such as the serial-parallel trade-off, fixed or floating point,      choosing sample rates and what precision to use
* Building blocks for digital control with ELMG’s licensable IP cores
* Using the ARM cores in the Zynq to your full advantage.

This webinar will be hosted and presented by Dr. Hamish Laird, ELMG Digital Power’s CTO and a Principal FPGA and Power Electronics Engineer. Hamish has considerable experience the design and implementation of varied digital control systems and IP for power electronics on FPGA platforms.

The webinar on Digital Control of Power Electronics using Zynq, which includes a short Q&A session, will be held on Tuesday 4th Pacific Standard Time at 10am and is available globally.

Spaces are limited.

Hands on Course – Digital Control of Power Electronics Training

This hands-on course aims to provide engineers with solutions to the key issues in digital signal processing, using microcontrollers, microprocessors, DSP and FPGA. These solutions can then be employed effectively in the digital control of power electronics.

Over the four-day course, split into morning and afternoon sessions, participants will be provided with targeted training on digital power electronics control covering the detail of both digital control and power electronics and how they go together.  They will gain the ability to close a digital power converter feedback loop in a stable fashion by following repeatable easily understood steps, as well as techniques to understand what the effect digital control’s limited bandwidth, processing power, number of bits and dynamic range have in digital power electronic control.

What you get from the course?

Engineers who attend the course will gain in-depth knowledge of the interaction of power electronics and digital control; this includes sampling and aliasing in the context of fixed and variable frequency switching power converters. There will be take away methods and steps to solve design issues such as one sample noise, precision limits in filters and controllers, non-linearity, quantization and other digital effects.  A copy of the slide slide presentation course booklet covering the material presented and lunch each day will be provided.

What do you think the biggest issue is when diving into digital control?

What do you think the biggest issue is when diving into digital control

This from D.P. -Lately to me it seems the biggest issue is maintaining a sustaining capability to the company where it is introduced. It requires at least one person that is decent at digital control design and then a team people that can implement. One person that can translate simulation to code, one person that can do state machines, one person that can do communications, etc. Lay on top of that maintenance and so on, it becomes a decent chunk of work.

Also digital technology changes so fast these days it can sometimes be difficult to keep up so you can take advantage of the advancements in processing capability and test capability. Many companies seem to fall behind because they don’t want to abandon their code base.

And this from J.F. – My take on this, as a former digital design engineer that now manages a power design group, is that it takes a very different mind-set to switch from analog power design to the SW/FW coding effort that it takes to implement the digital control algorithm. Since this discipline and way of thinking is foreign, it can be a major hurdle depending on the length of time the individual has been performing power design. Some of my folks are having an easier time to make this transition than others, but all are struggling to come up the learning curve.
