Hi all,
especially for those high power AX-topology amplifier a SMPS might be a cheap solution.. After some searching I found this: http://www.fairchildsemi.com/whats_n...yback-pfc.html and especially this one: http://www.fairchildsemi.com/pf/FS/FSCQ1265RT.html Do you think it is diy-able..... |

Yeah... of course... the real question is, do you understand it well enough to take it on, troubleshoot it and make it reliable?

LOL offcourse not... but I'm sure I will after some significant time reading all I can find on SMPS.... So far this seems this most simple SMPS suiteble for an audio amplifier ..but I if any of you have suggestion, I would be very interested..
I cann't seem to find any web pages with audio SMPS projects.. anybody got some links? |

Thijs,
No links, but I have been using these for some time now: http://www.vicorpower.com/products/d...dules/2nd_gen/ Just add a bridge and capacitor up front, and you have highly regulated, fully protected, 2 x 150W supply. Maybe not what you want, but a nice example of contemporary technology. Jan Didden

Nice, thanks for the link! I have looked up the prices:254$ for a dual 48Volt/150Watt modules ... although the look great, state-of-the-art, it isn't price competetive compared to a conventional DC supply and not very DIY...... but it is tempting!

48V will be very exciting in the next couple of years. Stay tuned. |
