Hi
Is there is a way to reduce or eliminate EMI from high voltage power supply, as its interfering with other electronics. I tried adding ferrite sleeves on cables, adding limiter resisters, the only thing I didn't try is to add RC snubber. ( waiting for high voltage capacitors to arrive). Any ideas?
Output voltage from power supply is 5kv
For plasma experiments

 

Is the supply powered from the AC mains?
What is the nature (frequency, waveshape, etc.) of the interference?

An AC EMI line filter at the input (examples) may help.

 

Thanks for the reply.
The HVP is from the main . It's a CO2 laser high voltage power supply. It's a DC high voltage. I will add this emi filter and try.

 

Hi,
is HV cable from power supply to the laser screened?
