Objet?: Re: [Amps] HV Switch Mode Power Supplies
I'd assume that the power supply would be put into a box with line
filters
and DC filters as well.
You want to make sure that there is no 40 KHz switching noise on the HV
to
the amplifier because it would plate modulate it producing 40 KHz
sidebands. However, I have found in other work that I have done that
getting rid of the DC output noise is relatively easy.
