regulated power supply

yugaaa · 14th June 2002, 07:29 PM

any body interested in joining me for building a regulated power supply for a power amp.the regulator should be able to handle 100v at 10 amps continuous.

What kind of power amp are you building that you need this type of voltage and amperage?

Are you interested in a switching regulator or a linear regulator. With linear regulators, they are essentially another power amplifier which require much of the same circuitry as a linear power amplifier. This includes heatsinks, differential amp, voltage and current amplifiers. Also, linear regulators are often slow to respond to transients and could limit the slew rate. A higher voltage than 100V must me generated and regulated down to 100V. What voltage range were you thinking for the input? What type of help did you need?

i have come across a lot of threads where the discussion is only about the output or the input devices,but in my opinion a good regulated supply will definitely make a mediocre amp sound good.that is the idea of starting this thread.by the way the amp which i am trying to build is similar to qsc 1310.i have got the pcbs made ,i run a pcb factory so in my spare time i did this one.for the voltage and the current specified i think a regulated supply will bring my cost down on the electrolytics and second thing is that i hope the amp will sound a lot better.
