Hi
Please talk about what SMPS topology are the best suitable for audio power amplifier(class a ,ab, b,d or true digital amplifier).The smps power is over 250w or 300w.
Re: What SMPS topology are the best suitable for audio power
8) use a topology which has the lowest peak currents.
A full bridge with active reset( UC 3875 )
one more thing your power supply should be completely shielded and should have multiple filtering at the output to get low ripple and noise.
Re: What SMPS topology are the best suitable for audio power
In terms of your original post, a smps topology would be class d. Class a, b, and ab are all essentially linear. I wrote an article in EDn a few years ago on class d that shows the difference from class a and b. Amazingly, it is still online: **broken link removed**
