Choosing The Right DC-DC Converter For Your Critical Medical Application
February 09, 2022 by P-Duke Power
White Paper Overview
The range of power solutions for electronic medical devices are as varied as the applications themselves. Between the power source (e.g., battery, outlet, generator, etc.), the power delivery network (PDN) and the connected circuitry (e.g, sensors, actuators, processors, etc.), it is critical that every component function nominally in the event of a power loss, voltage fluctuations, or potential interference.
This whitepaper from P-Duke Power covers the power considerations for medical devices, the basic parameters to look at in DC-DC converters in medical applications, and the power supply requirements for medical devices.
I know the topic is DC/DC converters and not AC/DC converters but the distinction of the barrier being between a primary and secondary circuit (as opposed to a secondary to secondary circuit) may still apply and from memory the creepage / clearance distances you are quoting are secondary to secondary level not primary to secondary (which are more stringent). Correct me if I am wrong by all means. I only mention it because it is an important distinction that I did not see in your article and understanding the difference, the reason for the difference and the implications makes the whole thing much more intuitive. It is also a critical thing to get right even for non medical devices so the potential benefit for other readers understanding this issue properly may be their life or someone else’s.
