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.

PSMA Software Firmware Reliability Improvement Report

Monday, December 2nd, 2019

Improvement of software reliability is a pressing issue in the digital control of power electronics. It is commonly reported by managers and executives in large power supply purchasing OEMs that most of the issues with power supplies are due to software problems.

Improving software quality for digital power

As part of an initiative by the Power Supply Manufacturers Association (PSMA) Reliability Committee, ELMG Digital Power provided research, examples and written material for the PSMA Software Firmware Reliability Improvement Report.

ELMG Digital Power is proud to be primary contributor to the PSMA Software / Firmware Reliability Improvement Report

Typical issues in digital power electronics

Typical issues in digital power electronics include

  • Limited modulator precision due to timer and clock speed
  • Numeric precision limits in digital filters
  • Excessive delays from limited processing power

Software quality improvement

As software quality is the result of following and implementing a repeatable process the report details how

  • Version control
  • Code standards
  • Defect tracking
  • Code reviews
  • Code inspections
  • Inspections before testing
  • Test specifications

are used to improve code quality.

How do you get the report?

Best way to get the report is to join the PSMA or you can purchase it.

Want to preview the report?

Improving Quality is the ELMG Way

We are all really proud to be part of the effort to create this report on improving the quality of software in power supplies. It fits really well with our aim to improve the performance, efficiency and quality of digital power electronics systems.

Digital Modulators have precision limits that arise from the limited timer clock rate of microprocessors and digital signal processors.  Possible effects on the control of the power converter includes

  • Poor steady state tracking
  • Limit cycle oscillation from slip-strike 
  • Reduced stability margins and possible instability

Choosing you power electronics processor effectively in Digital Power Electronics Development – Free Webinar

Thursday, May 16th, 2019

Tuesday June 4 at 12 noon PDT (3pm EDT)

How do you choose your processor.

Your Digital Power Electronics Processor Choice power electronics processor is crucial to success in Digital Power. And the key to choosing in a way that doesn’t end up creating delays in the project delivery.

So what are the most important issues to consider

Processing latency

Delays in the digital processor add phase lag and so can make getting stable operation at reasonable target bandwidth. Estimating accurately the delay that is acceptable and possible with possible target processors ensures that the processor will not run out of time during the development.

How to manage the limited number of bits

The limited number of bits in a processor means that there is a trade off between precision and dynamic range. The natural instinct is often to have larger dynamic range and lower precision. Best practice is to choose the opposite. Joins us in the webinar to see why.

Timer resolution

Likewise timer precision limits the available resolution in PWM and variable frequency modulators.

ELMG Digital Power are offering you the opportunity to attend our regular webinar on Digital Power Electronics. The next webinar is

In-house course digital power electronics

Wednesday, May 30th, 2018

We recently ran our digital control course in-house for a power electronics company.

Great group of guys and this is what they said.

“Everybody enjoyed the course, and it’s given us a lot of food for thought!”

Why choose in-house course digital power electronics training?

  1. Keep know-how in-house.
  2. Minimal disruption to your team.
  3. Everyone gets the same exposure.
  4. It’s team building.
  5. In house means no travel and travel can be hard to get approved.
  6. Have the teacher all to yourself.
  7. Great value when you add it all up.
  8. Emphasis on material specifically for you.

When can we have it?

Send us an e-mail and we’ll work a time out.

Is it the same as the publicly available course?

Yes – we use

  • #Teledyne #Lecroy scopes
  • AP 300 analysers
  • Boost coverters
  • Fyfe digital power platforms

It’s run by the same team

We also do the same workshop practical experiments to reinforce the learning.

Can you tell us who had the recent in-house course?

No. It is covered by an NDA so we won’t disclose which company it was.
