Need to build a simple mains power supply for linear amplifier (28V 30A)
The important is to limit the output voltage to 28V and have maximum
output voltage when input drop under ripple One solution I can figure out is http://www.noding.com/la8ak/12345/images/28vReg-4.gif another more commonly found solution is http://www.noding.com/la8ak/12345/images/28vReg-3.gif the advantage of the first over the second is that the it needs single supply voltage and the power fet can be mounted directly in chassis 73 Jan-Martin, LA8AK --- J.
