diode bridge 30A

[Patrizio88]

i'm building a power amp that i designed. I noticed that the triangular waveform shape of the ripple has an overshoot, a peg on the corner of the triangle. Using a fast recovery diode bridge could I improve? I need a 30 A diode bridge, can you recommend something?

That's very small resistance in wiring or inside the capacitor.

Did you use old, degraded capacitors , or not choose one with low ESR?

 

[Patrizio88]

I used 4700uf low esr vishay bc, 8 in parallel.

Ok, post the circuit schematic, and a photo of the waveform and the wiring.
How much current is this?

these are the pics... short wiring, this feeds 8x lm3886 with local bypass from 10nf xr7. at the moment of the measurement the amplifier was not driving any load

How about when loaded?

Bad solder joint?
