Dec 2, 2015 at 18:57 | comment | added | scanny | I was wondering about the unregulated moments question myself, and had actually observed it on shutdown on an earlier prototype. The negative rail was going down before the positive one, and so in certain load situations there would be a voltage/current pulse during shutdown. It went away when I adjusted the filter caps on the bias supply to make the negative one bigger (it naturally provides more current in the circuit). But I have to say I don't completely understand why there's not a complementary pulse on startup :) I'll test again before I wrap up the PCB. | |
