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.

Earthquake New Zealand

Monday, November 14th, 2016

All ELMG Digital Power People are safe

There has been an earthquake 100 miles or 160 km north of our base in Christchurch.

All our ELMG Digital Power people and our families are safe and well.

There is no damage at ELMG Digital Power in Christchurch and we are working as usual.

Our thoughts and prayers are with those who are near the epecenter of the quake.

Thanks to all who have sent messages of concern and support.  We are unharmed, well and working.

Please get in contact to catch up.

Four days

The course has been expanded to four days and includes lab sessions each day to reinforce the learning on

  • Precision extension of Digital Modulators
  • Digital Loop closing
  • The effects of delay
  • Loop measurement using the control processor.

What people who have attended say about the course?

“Had very high expectations of this course. Hamish delivered. Excellent for power engineers who are starting digital power. Thanks for putting this on…I only regret it is a 3 day course. I could sit here for 3 more days”

“This course was full of critical material not found in the app notes.  Very enjoyable and well taught.”

“Good course. Hamish knows his material. I’ll be able to apply this coursework to my work.”


“I would highly recommend the ELMG digital control course to all power electronics engineers.  What makes this course particularly valuable is in the practical approach and relevance to the control of power electronics.  The topic of digital control is a very broad subject and hence the specific challenges and applicable tools are very different depending on the application details. Many digital control / DSP courses try to approach the topic from a very generic broad approach, treating all applications in the same way.  The classic approach involves starting from a conventional analog control model and then adding ADC and DAC blocks to change between the analog and digital domains with a digital controller replacing the traditional analog controller. The problem with this classic approach is that it is not a practical or applicable method for designing high bandwidth controllers for use for the control of power converters. The ELMG digital control course specifically focuses on the control of power electronics and hence the course only considers concepts and techniques that are applicable to the control of power electronics.  The course covers a wide range of digital control theory and introduces the power electronics engineer to all of the state of the art digital control concepts.  This course is a must for any power electronics engineer who is involved in the digital control of power converters.”
