Xilinx Alliance Program Re-Certification

ELMG Digital Power and the Xilinx Alliance Program

ELMG Digital Power and the Xilinx Alliance Program is an ongoing, valuable and extremely valuable partnership.

When asked about this ELMG Digital Power CTO,  Dr. Laird said

“Maintaining ELMG Digital Power’s commitment to providing exceptional service and products is our key uniqueness. To this end we are pleased to continue in the Xilinx Alliance Program membership.  We see great things happening with Xilinx All Programmable FPGAs and Zynq SoCs, UltraScale devices and the Spartan7.

It is great to see the capability of the Vivado Suite continue to allow exceptionally fast, reliable and robust development flows.  We are really pleased to continue with ELMG Digital Power’s Xilinx Alliance Program commitment and are please to be part of the Xilinx community.”

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

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

ELMG Digital Power Pays it Forward with Red Cross

ELMG Digital Power are pleased to announce that the “Pay it Forward” charity for the coming year is the Red Cross.

The Red Cross

Each year ELMG Digital Power chooses to support one charitable organization in their efforts to help.  This year the Red Cross are the recipient.

ELMG Digital Power CTO Dr. Hamish Laird explains.

“During any disaster or humanitarian crisis the Red Cross can provide assistance, expertise and money to those in need.  The Red Cross is a great organization and we at ELMG Digital Power are really pleased to contribute to having the Red Cross be successful and helpful.  Their work around the world makes a significant difference. ”

 

Donate to the Red Cross

The Red Cross is a excellent charity to support.

Pay it Forward

The ELMG Digital Power “Pay it Forward” charity program supports one organization per year. Previously we have supported schools for teenage mothers.

In-house course digital power electronics

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.

 

Equivalent bits – a question from LinkedIn Group

“I was looking through ELMG’s tutorial “Three Key Issues to Watch out for in the Digital Control of Power Electronics” (https://www.elmgdigitalpower.com/power-electronics-digital-control-free-report-on-three-key-issues/) and am having some trouble understanding the relationship between frequency, register size, and equivalent bits.

An example given in the “2. Timer Precision” section of the document reads:

‘Consider the case where the timer clock runs at 40MHz. If the variable period oscillator register has 256 bits then the maximum frequency that the VPO can make is 10MHz and the minimum is 39.0625kHz. The example LLC resonant power converter needs a variable frequency of 500kHz to 210kHz to perform the control. This means the VPO count register has a usable range from 80 to 191. This is 111 counts which is 6.8 equivalent bits or almost seven bits.”

Equivalent bits are a great way to look at numeric precision.

Come join the discussion to see how equivalent bits is calculated.  https://www.linkedin.com/groups/6677852/6677852-6242781250545942530

 

 

For your Digital Control Workshop which Micro Controllers are taught?

For your Digital Control Workshop which microcontrollers are taught in the class?

Texas Instruments?

Thanks John

 

Hi John,

The uniqueness of the Digital Control Workshop is that it is not focused on one microcontroller family.  We cover the key know how that ensures you and your team will get your digital power supply robust and reliable.

Here at ELMG Digital Power our platform is an FPGA based power converter controller that we have developed.  We sell power electronic specific FPGA IP blocks for PWM, filters, three to two blocks and all the other required power electronic blocks.

We have development experience in using processors for power electronics control from

  • Xilinx
  • Atmel
  • Microchip
  • STM
  • AD and
  • Ti

Our course came about when and R and D manager asked us why his team had knowledge gaps that we were now helping fix.  These gaps were common across a number of our OEM clients.  We address these key common knowledge gaps in the course.

Happy to have a netmeeting or skype call to talk through this at anytime.
