    d3k high power class D

    Here's my d3k amp.It sound's good.No hiss or noise in speaker.Output DC max +/-15mV It use separated and isolated gate drive which is recommended for high powers.It can operate from +/-6 to +/-120V.For higher than +/-120V there's another circuit but it's almost not needed that high power...

    smps3k

    Hello all :) I try to make simple but powerfull SMPS for audio amp. or similar equipment. I have one IGBT brick SKM75GB123,and I like to use it in SMPS. This IGBT isn't for high frequencies,and this means that oscillator must have f. about 20~30kHz. I make a simple oscillator like from CFL bulb...

    1.2kW SMPS from junk parts,low cost

    Hello,here's my 1.2kW SMPS built from junk parts.It's really simple and good. SMPS is in fullbridge,uses 4 same switching transistors,you can use 13007,13009,2sc2526,BUxxx,BUTxx,BUVxx,and more.... This is self osc. SMPS For power transformer you can use two EE33 in series,one ETD49,or other core...

    Uni SMPS 300W

    Here's my smps,all parts is from at/atx pc psu.I'll tested it,and works great.If it don't start to oscillate,reverse feedback windings (15k resistor goes on it).Feedback transformer is original EE16/19,not rewounded.Output rectifier is on another board.Schematic and pictures:
