A mechanism for obtaining two independently regulated voltages from one single supply circuit.

SMPS, or Switched Mode Power Supply

For several years now, E.D.&A. has been developing and integrating a Switched Mode Power Supply (SMPS) into its electronic controller designs. It’s a replacement for the traditional transformer. The reduced standby consumption and the reduced use of copper make our electronics “greener”.

It is not so difficult to obtain different voltages, with a mutually fixed ratio, from one power supply. With a dimmable LED power supply or a motor controller, we also need a variable voltage besides the constant voltage for the control circuit. This therefore means that all other voltages vary too, which is not always desired.

Unique, innovative solution results in a patent

A traditional solution is to create two switched mode power supplies next to each other: one constant and one variable with two separate transformers. Or you need an additional converter to regulate the voltages. This had to be made more compact and flexible, because we wanted to integrate this into one single coherent and cost-effective design. After a great deal of research, we found an innovative solution. That solution turned out to be so unique that we patented it.

This first patent fits in perfectly with our innovation strategy, because 35 R&D engineers are now at work on tomorrow’s applications. So it’s by no means out of the question that even more patents will follow in coming years.
