FAQ:
Q: Is this a good power supply for 40$?
A: For 40$ is not to bad. But as with most inexpensive switch power supplies it does create quit a bit of noise on 80 meters. I found that leaving the line in ground off helped a lot. Also made a common mode choke for the outputs. Can also benefit from a inline choke on the input.
Q: What is the best linear power supply circuit for power supply?
A: A linear power supply circuit is a better choice. Because it is so easy circuit. We often use the three-terminal regulator IC likes 78xx, 7812, or 7815. But It is a big size with large components. For example, the transformer if you want 30A output current. So you need the least of 30A transformer.
Q: What size capacitor do I need for a 30 amp power supply?
A: In 30A output, if you cannot buy a 68,000uF 25V electrolytic capacitor. You may use 10,000uF 25V x 6 connect together in parallel. It saves money and easy. For example you want 20,000uF you can use 2x 10,000uF.
Q: What power supply do I need for mot rewired?
A: With the MOT rewired transformer (used in my design), bridge rectifier and smoothing capacitors specified and using four 2N3771 pass transistors, the supply should be capable of producing more than 60 amps at 13.8 volts output. The mains input can be taken to a 6 amp mains filter. This filter is optional and was not used in the prototype.
