--- Quote from: Wolfgang on November 04, 2018, 12:40:02 am ---The ARRL (American Radio Relay League) has some 30V/10A supply suggestions. Important things are: - adequate cooling (fan) - bridge rectifier with sufficient current loading capability (20A min) - 4 x 2N3055 - frequency compensation (see ARRL schematics) - overtemp protection - output crowbar to protect your load if something goes wrong. http://www.dd1us.de/Downloads/an%20rf%20proof%2030%20amps%20power%20supply%201_0.pdf --- End quote --- Power supply doesen't need stud diode heatsinks, D1 & D2 studs can be replaced with a few ganged high efficiency schottkies dpak or other smt parts. Aren't electrolytics inappropriate for mains side applications? |

LaserTazerPhaser - "Aren't electrolytics inappropriate for mains side applications?" The capacitors you marked are not polarized. The curved electrode generally indicates outside foil. There is no + or - that you would see on electrolytics. Check the values and you'll see they can't be electrolytics. |
