I have a friend who is designing the power supply, and now he wants to enter the field of medical-grade power supply, the output high voltages of the power supplies are -10KV, -20KV, -30KV, -40KV, but he does not know the safety, what should be paid attention to at the output end of the power supply, what matters meet safety?

I was wondering if anyone has any information, explanations or links on this.

Thanks for your help.

 

It has been a while since I designed a medical power supply.
I had to add one extra layer of insulation in the transformer(s).
I had to measure the leakage current. (primary to secondary) and keep it below some level. (AC and DC)

Thanks for the info, do you have any info about the safety of the output high voltages of the power supplies?

This thread was focused on the output side, he also concerned about input side in the future.

 

Leakage current is probably the most difficult challenge in getting a power supply to meet the needs of normal patient-connected power supplies.

It is a good idea to obtain the relevant safety standard for the type of product proposed and for the country in which it is to be sold. That part may be expensive, but that's what you really need to do.
