soft start for powerhead

[titus]

Hello,

How about this:
V(t) = 1.414 * 120 * (1 - exp(-t/TC)) * sin(2*pi*60*t)?

This is something we all can do with an integrator-and-dump circuit preceding a transistor current driver. We'll let Darren to actually put it together. [img]images/smiles/icon_biggrin.gif[/img]
