The digital power electronics industry is global as are the development and test teams.
For a power converter loss reduction project we worked in New Zealand on the controller for a power converter. Our engaging customer was in Sweden. The other part of the development team was in Pune, India allowing the Swedish customer to leverage ELMG expertise and Indian cost advantage.
We at ELMG provided the technical oversight and project direction for the system via conference calls and web meetings at times that suited. We shared design details, tests results and specifications via online project management system ProjectNet.
ELMG designed and tested the controller in New Zealand. When all the parts were ready ELMG people travelled to India to the run up of the controller and integrate it with the power converter and controller.
As Dr. Hamish Laird, ELMG CTO says
“India is a great place to work and the cultural affinity that New Zealanders and Indians have is fantastic. The common interest in cricket helps greatly.”
The traction converter for a hybrid SUV was developed in a European country by a company who are sub-contractors to a Northern European company which in turn is owned by a large American company. ELMG expertise provided a detailed review and design suggestions for the digital control and the power converter implementation. The final customer for the power converter and controller is a Chinese automotive manufacturer.

We often are contractually bound to not disclose the details of what we work on and who we work with. This makes having references on our website difficult with commercial arrangements and NDAs. Our solution to this is when you’d like to talk to some reference customers then we put a non-disclosure agreement (NDA) in place between you and ELMG. This NDA then covers the information you receive from our referees. We do have a few trade references.
“Your vision is extraordinary. You offer your customers far more than a design and development service. The people who make use of your business and market knowledge, utilising your national and international contacts, would be your most satisfied customers. My main regret is that we cannot utilise you to your full potential.”

“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.”

“Every time! It demystifies compliance testing. It gets it inside the design process and it changes our relationship with the test labs where we understand exactly what we need done and why so that we can control the process, instead of delaying the expense until the end, when the goods just disappear and come back pass/fail.
This all needs to be understood widely in the manufacturing community and become a part of design thinking from the moment the graduates start learning about designing things.”
