Hi all This is the car amp's smps core It's 4x70w(280w) and class ab Smps ferquency is 50khz Skin depth in 50khz is 66/223.6=0.3mm Pri current in each rail is: (280x2(efficiency about 50%)/12)/2=23A In this amp pri winding is 3 layer of 0.8 wire and we need to give 7.8A from per layer But How...

Hi all. I want to make an amplifier with TL494 Does anyone have a tested schematic? not with Full Bridge for double voltage thank a lot

Smps This is my core for 200w smps power (100w amp power): and this is for 4x80w Marshall Amplifier: How is the core computation of the converter?? (Which is the size of the wire too small (the wire thickness is higher) and its low drop) Circuit Frequency is 32Khz but i can change...

Hi all I made TL494 push pull Smps for car amp(No feedback) my test amp is 100w. i tested with AWG26 wire and output Dropped from 32 to 17 volt in 60% music volume core information pri:5+5 turns(17 Layer) sec:13+13 turns(7 layer) i Calculate for 200w smps power.(Double AMP power) but there...
