el wire...

Post by mtbf0 »

i'd like to play around with sequencing el wire. there is a ton of information about switching the ac to different strands using triacs, which is fine as long as one has at least one strand lit at all times. question is ... what if i want to turn the entire display off for a while. my understanding is that with nothing connected the inverter voltage will increase to the point that the inverter itself will fail. can i just switch the power to the inverter itself with a bipolar transistor?

yes or you can switch it to a loading capacitor!

The preferred solution of the two probably depends on the duty cycle...how often will it be off, and for how long?
