Breas Medical Grade Power Adapter Solution

Breas Medical Grade Power Adapter Solution

The Challenge 

Provide a low cost, consumer-priced, AC/DC Medical Adapter for portable CPAP machine. 

How We Delivered 

The original power supply used by Breas was not ours. At the time we were contacted, it had about a 10% failure rate in the field. Not acceptable. We received the Z1 CPAP machine and immediately analyzed it in our lab. We found that when the person using the machine coughed into the mask, the CPAP device sent a voltage pulse back into the output of the power supply, thereby shutting it down. We implemented several modifications to our power supply which fixed the problem entirely, allowing Breas to ship problem-free product from then on, until today...and beyond.

What We Did 

Armed with a power supply, components and filters our Engineering Manager drove from our facility in Hudson Massachusetts (USA) to meet Normatec at the EMC lab. First, we tried our standard power supply however this failed EMC. Upon a deep review of the frequencies in question, we realized that the noise was indeed not coming from the power supply but coming from the Normatec unit. Additional filtering was going to be needed, but there was no room in the Normatec equipment for any further filtering. 

Based on the frequencies and the attenuation needed, we changed the ferrite EMC filter on the power supply output cable, so that it would have the attenuation needed at those frequencies. We hand-built a unit while at the EMC lab in our commitment to get the job done. The test was repeated and received a solid pass with more than 6db of margin. We then re-tooled the ferrite EMC filter on the output cable which now had multiple turns on it, and we were able to solve the system level EMC issue.
