"40w fluorescent lamp inverter"
Hi all,
I just made this "40w fluorescent lamp inverter":
http://www.aaroncake.net/circuits/40wflamp.htm
It works perfectly. However 40w is rather to big for me and I change it to 20w lamp, and still works but did not recomended by the author.
Then I made an experiment, reducing the secondary wound from 450 turns to 250 turns and still can light up 20w lamp!
The question is: am I in the right direction with my experiment to make more efficient for 20w lamp?. if not what should I change to make this circuit works efficiently for 20w?
Another question: how to protect the transistor from being exploded, when no lamp being connected to the secondary wound? Can I use 0.33nF/1200v in series with the lamp?
Thankyou in advance for you help.
Gunawan.
