I've searched a bit to see if this topic has been discussed before, but it seems that it has not. So...
...even when you wire your PW switches to use auxiliary power, when you throw a switch you get a dimming of the lamps. This makes perfect sense, as the switch coil draws high amperage and thus the voltage will tend to drop (which dims the bulbs) unless/until the transformer can react to re-establish the original voltage again at the new, higher current draw. In a DC circuit you’d smooth this periodic ripple by a combination of filter caps and chokes/inductors. But, in an AC circuit, is there a simple way to do the same thing?
Concepts I've come up with so far include:
- Switching in a couple of volts of DC when the switch is thrown to make up for the voltage drop at the lamps.
- Wiring up something akin to the "boost" circuit used in PW transformers for upping the voltage when the whistle is engaged.
Would appreciate any thought or suggestions!
