I have seen, but cannot find again, a really simple implementation of a mains soft start circuit. The thing I'm thinking of involves a power resister inline of the mains. When the device is started, current is restricted until a relay is energised, which shorts out the resistor allowing full power
The thing is, I can't remember (and so can't decide on) a good way to energise the relay after a second or so.
Does anyone know of a link to a reference implementation for such a circuit?
