It doesn't produces RF noise at all. If noise doesn't matter for you and you want to get better efficiency and lightweight power supply, then switching power supply is your choice. For example, if you're need power supply for home heater, electric stove or powerful electric motor, then switching power supply will be better than linear one. But if you're working with analog electronics, amplifiers, VCO, DAC, ADC and other analog stuff, then linear power supply is better. |

Yes all what I make my self, could easily be with linear psu, but some of my lab gear has smps in the plug side on the cord, my shop light is LED and fluorescent lamps. I hope to build smps myself so it would be nice if the other did not make noise to. So I do not have the easy choice to "just don't use smps", therefore my hope on reducing there noise without going overboard. |

try to put RF choke ferrites on all wires. As many as you have, on any wire in your lab, like paranoic. It can help for a little ;D |
| FriedMule:
great idea, and how do I shield the smps to chaise noise? Dave talks in a video about a cast alu box for shielding, would that contain the smps-noise inside the box? |
